There are two stomach that I know of directly shown in this video. The first stomach was shown to indicate its shape, size, and relation to the small intestine. The second stomach was the wrinkly ball shown in the thumbnail. He we just trying to show off the inner lining of the stomach to show it’s ridges.
Something like processed meat and knowing how it got from poor animal to burger is far more disturbing than seeing a human stomach but youre just so used to it you dont care
For those who're wondering why the burger isn't really dissolving in the stomach acid which is meant to be strong. Your stomach acid is not just HCl. It's HCl coupled with activated pepsin which is responsible for proteolytic digestion. So, that whole piece of burger has proteins as well as fats and other stuff. It's not meant to dissolve completely. But also, stomach doesn't digest food or dissolve it. It just keeps it semi solid when it is passed down the deodenum! Hope it helps!
Sorry but enzymes and pepsin come from decomposing food. Many experiments have been done with pepsin and enzymes. Nothing happens. The best digestion is to chew your food well, because massicating is the digestion. Other wise if you don't chew your food well, it will come out the same way. The medical system should not be trusted blindly.

All of my life I thought the acid is to break down the food into even smaller bits. ...and I had biology in high school for 9 years. Lol. I feel dumb now.
Its the enzymes in stomach that breakdown the food, the stomach acid is there to provide a optimum condition for the enzymes to work in. - a biology student :)
really cool and scary how just the enzymes + 0.155m/L acid work as well as 12m/L acid. It would've been nice to see some enzymes poured in there as well but i don't want to be demanding lol.
As someone who is studying chemical engineering and works constantly in labs, seeing and understanding everything he did brought a smile to my face, been a fan of science since been a toddler
Having acid reflux, let me tell you, it feels like you swallowed a glass of pure acid in your esophagus. It is very painful and causes me to cough so hard and wakes me up from a dead sleep. So grateful for medication.
i go through this when i digest certain foods though i think mine is from having to take too many antibiotics to counter several infections i had earlier in the year, just feels like im digesting pure glass shards everyone thinks im dramatic 🥲
Imagine if someone ever told you that your stomach would be laying on top of someone else's while being recorded for a video someday. It's mind blowing
As a SEVERE GERD sufferer, it's amazing to see how little hydrochloric acid is truly in our stomach acid. It feels so much higher when it's burning away in places it doesn't belong. My GERD was so bad and improperly treated for long enough I now have a ton of scar tissue in my esophagus and have to go in for dilation every couple of years. They get it all stretched out laparoscopically with a balloon and it's an immediate difference. I know it's time to go back when I start feeling like things are getting stuck in my throat/I start choking while trying to swallow. While I know it's actually further down that the food is sticking, it's so interesting the brain tells us it's in the throat. First I can't swallow proteins, like chicken, steak, turkey, etc. The next phase is breads, pasta, etc. When I am ready to go in for the procedure, I can barely swallow my own spit and other plain liquids. It tends to happen in a quick succession... Like a couple of weeks. Due to the scar tissue and damage, I'm at high risk for Barrett's Esophagus and esophageal cancer. Hopefully proper treatment the last few years will prevent anything like that. If you are having issues with heart burn and/or reflux and it's not clearing up quickly with OTC products, PLEASE get to your doctor! They can refer you to a gastroenterologist yo get yourself checked out. It usually involves an Upper Endoscopy, which is absolutely NO big deal. The worst part for these types of treats is the prep.l
I was on two rounds of protonix, the first time dint really work but I was also not dieting right, the 2nd time it worked much better cause I had a better diet. Still have heartburn but nothing like I used to. And I'm also able to swallow foods way better than I used too. It got so bad that i couldn't eat anything without drinking something with it, it sucked. Definitely get it checked out asap. The sooner the better.
Disclaimer on behalf of this channel: Not all gloves are created equally either, don't go thinking random gloves are going to protect you against everything.
@@Frassboss90z Made me laugh 😄 The blue gloves in the video appears to be medical grade nitrile gloves. There are thicker nitrile gloves on the market, generally a safer option for working with certain chemicals. I can't give specifics as I haven't worked in the field for ages, forgot most of the stuff. You could google the data sheets for whatever you want to work with which should tell you how to protect yourself. Or you could just not mess with chemicals lol.
Industrial Hygienist here and I concur. Always check the manufacturer guide of your chemical gloves. Most have permeation guides to let you know if they are sufficient for protection.
I'm in a less than ideal spot financially; I am no longer in high school. But these educational videos assimilate knowledge for me in a way that's entertaining and helpful for me to retain. Thanks for showcasing the demonstration that I can't get from school, I'm glad to learn anatomical science here.
@@roseberry-nj2ux or maybe he was forced to learn like every child is , some get adapted to it and some fall out and later they find something like this interesting. And there are many more reason that stop you from actual learning in schools.
@@abhayagarwal5097 Yeah, I'd also argue highschool isn't the best place to expand your mind. Even when I was in school, before I had to leave for work and family problems, only a small portion of my knowledge came from school. In fact, me egressing from school to standard life has undoubtedly allowed me to integrate more knowledge by it being stuff I *choose* to learn. I essentially have my own curriculum on my own terms. No bounds, no sense of deadline nor a looming head telling me I must learn specifically what is in front of me.
Spicy food tricks your brain into thinking that your mouth is “on fire” - the brain gets the same signals as if it was actually on fire. When the Capsaicin gets into the nose your body tries to flush it out which is why you get a runny nose - you may also experience drooling and watery eyes. When the capsaicin (what makes spicy food spicy) gets into the stomach it stimulates the production of gastric mucus which temporarily speeds up metabolism. When your stomach works to digest the spicy food you may experience pain but it’s not causing actual damage. Here’s is the whole process: 1. Capsaicin binds to pain receptors on your tongue. 2. The brain cools the body by sweating, salivating and producing mucus. 3. Pain receptors in the esophagus causes a burning sensation in the chest. 4. The irritated phrenic nerve may affect the lungs which causes hiccups. 5. Pain and cramping the stomach occurs. 6. The rate of digestion increases which causes diarrhea. 7. Perianal burning may occur. Does that help?
@@Xdetonando it doesn’t specially help with weight loss, you won’t lose weight by just eating spicy foods. However, as spicy food reduces appetite and increase energy expenditure it can help with weight loss but don’t use it as only one option. Does that help?
@@prapanthebachelorette6803 Hi, in the first paragraph I did answer this but I didn’t really make it clear 😂. So when the capsaicin enters the stomach sit produces gastric mucus which temporarily speeds up metabolism. Is that more clearer?
Important safety info: when diluting hydrochloric acid, always put the acid in water and never the water into acid!! The dissociation of H+ and Cl- ions in water is a highly exothermic reaction (it produces lots of heat) which can evaporate water if the water is in small quantity (when you just started pouring). If you pour the water in acid, this can bring hot acid droplets onto you! Be very careful and always take safety measures like gloves and goggles, like this gentleman here. Great material, by the way! ;)
diluting hydrochloric acid isn't particularly exothermic. Also, always put the liquid with low heat capacity into the liquid with high heat capacity, i.e. when preparing 90% sulfuric acid from 96% put the water in the acid.
I never understood biology clearly in my school days... But i fully watched this video... because of how cool this man demonstrating with pretty good accent..... Loved your channel
15:25 this part where he tries to show us the fizzing is so adorable. Also the curiosity that he had to have to drop acid on the latex glove. I hope we have more people like this in science.
Fun fact, a nitrile glove is actually latex free. It protects against chemicals. Nitrile gloves are used alongside latex gloves in the medical field for those who are allergic to latex. I work in the PPE industry and absolutely love how deep it goes to protect people in various working environments.
I'm in nursing school and these videos are amazing. They help me understand what's actually happening in the body when we have certain conditions and will hopefully allow me to explain things better to patients once I graduate.
Me too. Been watching all kindsa human anatomical stuff on this channel for quite a while & the burger in acid experiment is the first time I've actually gotten nauseous. LOL
One issue with the meat in the stomach acid... when it’s in your stomach it is chewed and therefore has a much greater surface area. This will make meat of the same volume dissolve at a faster rate.
This absolutely makes sense! The stomach acid isn't designed to obliterate anything you eat. It's designed to break down the proteins in food and make your food easier to digest. If it obliterated your food, then that's counter productive because your food would be gone. Edit: just got to the end and I literally just said what you said. LOL great video!
As an Italian I’m always amazed to find out pretty much every name used in anatomy is in fact an Italian word some of them still used in modern Italian
@@thanoof the fact that they derive from Latin (which btw everybody knows) has absolutely nothing to do with what I was saying. Modern anatomy was consolidated during the reinassence and most of the terms were invented by Italians like Da Vinci ecc. Not Ancient Romans so…still amazed some common Italian words are being used in English anatomy.
Well, Latin is considered the language of Science. You can say similar things about other languages like; German is a language of command (Great for Dog/Pet training), English is a language of Trade (Culture Melding, Global Colonization and the Internet), ect.
One of the most scary things I have ever experienced, was being suddenly waken out of my sleep, taking deep gulps of air, feeling like I was being suffocated with this strong burning sensation in my upper chest. My initial thought was that I was suffocating somehow, and so I was literally *heaving* breaths trying to get it under control. Took about half a minute for me to realize just what had happened, when I noticed the taste -- stomach acid had crept up the esophagus and into the lower throat and the pain of it tricked me into thinking that there was something wrong with my lungs and my body responded by taking in huge breaths of air and also triggered the fight-or-flight reflexes as well as waking me out of sleep. Thankfully that has only happened to me like 2-3 times and the second time and beyond, I recovered quicker because I know exactly what it is now. The first time was damn scary, though.
Also, one more observation: you dropped the meat in, as one big chunk. This serves as an excellent demonstration of why you really need to chew food properly. Breaking it down into smaller pieces makes it easier to dissolve and break down (because breaking it into smaller pieces vastly increases the surface area being exposed to the acid). If you don't believe me, you can reproduce this effect with good ole ice. Get two ice cubes, smash the one into tiny bits and leave the other alone and let both melt. Note how the former is reduced to pure liquid much faster than the latter.
@@rambofirst2052 No. It just _feels_ like you have shortness of breath, but you really don't. It's your body overreacting to the pain in the esophagus.
hi this video is great and I love this educational content .However, there is a wrong fact at 5:51 you said that the increase of acidity between ph 7 and ph2 is 50 times due to the fact that the difference between ph7 and ph6 is 10 fold but, the ph scale is logarithmic meaning that the difference between ph7 and ph2 is ten to the fifth power not ten times five. However I do not wish to criticise this channel as I love your content.
Yeah pH is a logarithmic scale to the base 10. Which means pH is the exponent to 10. So going from 7 to 2 is 10^5 x increase. Or 100000x increase in acidity. More appropriately, increase in H+ ion concentration.
The anatomy and physiology of the stomach has always fascinated me. It contains an acid with a pH so low, that without a thin lining of cells and mucous, the acid would eat through the organ itself. Seeing the effects of NSAIDS and how they inhibit this protective layer is a good common example of a stomach being eaten by its own acid.
I've been browsing RUclips for 14 years. You are the first video that i ever liked. It's clear why your in the medical field. Your curiosity to learn is apparent. You touched on every single point and angle that i was inquisitive about when it came to hydrochloric acid. Thanks for the video. And yes i fell asleep during the math part and when i woke up i continued the rest of the video
This guy does such a great job in every video making things entertaining, interesting, and easy to follow. And usually does a good job on describing things, which helps because I'm blind. Good on you, man.
@@themonsteraddictmmxvi1564 Uh, dude, how? The meat used for menudo is literally called tripas, meaning guts or stomach. It doesn’t matter what it is. It tastes good.
I love how passionate he is about his videos! I can hear it and it makes me want to know more and actually learn from him. Teachers could take a page out of this guys book. I almost with I was an anatomy major so I could really appreciate it.
I've no qualifications in medicine, anatomy or even science. I was discouraged from doing chemistry at a higher level by my school & parents because I was a girl. 😠 But I've always been fascinated. I can't get enough of this series. It's fantastic & easily understandable for someone who last studied sciences as a 16 year old in the 80s, apart from an in-depth MOOC in nutrition offered by Stanford a few years ago. Thank you for doing these videos. 🙂

For those with frequent heartburn, I would recommend seeing a GI doctor to get it under control and prevent damage to the esophagus. I was diagnosed with Barrett's Esophagus this year at age 29. In my case, for the rest of my life I have to take a type of medication called a PPI (proton pump inhibitor) that reduces the amount of stomach acid produced. Although a small percentage of Barrett's patients get cancer, it is still a higher risk. Fortunately, there are procedures that can be done to lower the likelihood that it progresses to cancer.
so freaking knowledgeable and his delivery is awesome. No pretentious crap. Love this stuff! I bet this guy could've even taught me maths at school - he's so interesting!
Thanks for the calculation. I did that in chemistry, way back in high school without a proper understanding of what I was calculating. It makes more sense now.
I wish I had a gastroenterologist as enthusiastic about helping me and my gastritis and ulcers I've had for over a year as you are about teaching and learning anatomy and pathology
i love he does not only do experiments which is the main focus of this video but does silly little experiments outside the main focus of the video out of curiosity which sparks in curiosity in me and thats an amazing thing it was an amazing experience to watch this video!
Omg, love so much this video it is very well explanatory, and everything is subtitled, which makes it easier for us foreigners to understand (I'm from Brazil, so contents like these are not easily found in portuguese), thank you
Thank you so much for being so good at teaching and doing what you do. I've learned so much from your videos. I love the human body and the nature itself, you help me understand it. Thank you so much
This was very interesting. I would like a part 2 of this video where you guys discuss the enzymes involved in food digestion. I am lactose intolerant, lol where did my lactase enzyme go?😅
I have ileostomy so the lower GI info would be great as I have has peristomal issues n been eaten raw & other not so pleasentness that came from decades of fighting ulcerative colytis, abdomen surgeries n permanent ileostomy, rectal stump removed & so on... I have seen n learned alot with Doctors & Nursing staff as a patient n despite it all still make them laugh & brighten thier day no matter what I may be going through. I appreciate my team & Thankful people like you are teaching the newbies. Gives me hope for the Doctors &so on of the future💯🙌🥰
Isn't lactose intolerance more a genetics issue than a gut lining issue? At least that's what I remember from school...I seem to recall there being different levels of intolerance from mild to severe based on how defective the genes are. I can't wait to see the physiology aspect of it all.
This is crazy, I thought most of it would go over my head but you made even the math understandable. I would have seen chemistry and human anatomy in a much more positive way if I had a teacher like you in school
Does the "pseudostomach acid" have a required temperature ? since our inside of our body or our body is warm . does the temp. would make it a difference ?
chemical technician in HCL production here, we produce the "37%" HCL aswell and it is not that instantly harmful to the skin like many people tend to think, just don't get it into the eyes and make sure to wash it off the skin quickly with enough water and there will be 0 burn marks or whatever :) from my experiences the fuming of the high concentrated HCL is way more dangerous. long story told, wear your gloves, eye protection and make sure to only work with it under a fume cupboard like he did.
It eroded all of my back teeth from both pregnancy and Crohns related vomiting for years. If my doctors had told me to rinse my mouth with a baking soda solution after throwing up I probably wouldn’t have lost those teeth!! That acid is no joke 😳
Same thing happened to me from nearly a decade of unproperly treated severe GERD coupled with dry mouth issues from medications. I am 38 and over half my teeth are either gone or rotted out. Will need full dentures very soon on the upper.
Why don't you rinse out your mouth with at least water after being sick? Otherwise you just get a disgusting sick taste/smell in your mouth i always do that although I barely ever actually throw up
Blue :] so true... If Dr Jonathan had been my teacher in Biology and Chemistry.... I would have been a famous scientist today. Instead, I just digest my food and watch LOTS of RUclips.

I've been watching a lot of Sunny lately. This haircut is exactly the one Dennis had when he delivered the line "there's no denying that the skin is the most fascinating part of any animal" This guy is who Dennis would be if he hunkered down and took his doctoral studies seriously
Amazing... my random Google searched question from my sleepy thoughts brought me to this awesome science experiment. Thank you!! I'm so satisfied with the outcome.
For those interested. ,The Stomach acid still goes down further the digestive system, in the Duodenum, thanks to the Pancreas and some cells of its own, the ph of the acid increases, making it "non-lethal", since none of the other digestive organs have the functions to increase the ph, nor the "mucus" to deal with it for too long (note they all have mucus but different kinds).
Okay ngl or exaggerate anything but today, after all these years of studying chemistry & biochemistry in school, I've got a clear understanding of the basics of molarity and that too in just a few seconds! Also, I've recently discovered your channel and loving EVERY video and your concept clearing ability!
Once again...another excellent video. I'm actually concerned about having Barrett's Esophagus and my mom recently passed from Esophageal cancer so I am definitely going to see a GI very soon. Thanks for the amazing explanations. I love Anatomy!
I have seen dead bodies being handled like a heavy toy. Makes me realize we are nothing n that life exist when we are using the breathe of God. The moment he takes it back we are truly nothing....

We appreciate you and all the human anatomy content you put up for us.
As a SEVERE GERD sufferer, it's amazing to see how little hydrochloric acid is truly in our stomach acid. It feels so much higher when it's burning away in places it doesn't belong. My GERD was so bad and improperly treated for long enough I now have a ton of scar tissue in my esophagus and have to go in for dilation every couple of years. They get it all stretched out laparoscopically with a balloon and it's an immediate difference. I know it's time to go back when I start feeling like things are getting stuck in my throat/I start choking while trying to swallow. While I know it's actually further down that the food is sticking, it's so interesting the brain tells us it's in the throat. First I can't swallow proteins, like chicken, steak, turkey, etc. The next phase is breads, pasta, etc. When I am ready to go in for the procedure, I can barely swallow my own spit and other plain liquids. It tends to happen in a quick succession... Like a couple of weeks. Due to the scar tissue and damage, I'm at high risk for Barrett's Esophagus and esophageal cancer. Hopefully proper treatment the last few years will prevent anything like that.
If you are having issues with heart burn and/or reflux and it's not clearing up quickly with OTC products, PLEASE get to your doctor! They can refer you to a gastroenterologist yo get yourself checked out. It usually involves an Upper Endoscopy, which is absolutely NO big deal. The worst part for these types of treats is the prep.l
Get well soon!
Hugs! My FIL passed from esophageal cancer back in 2000. I pray that you are able to avoid it.
Hope you feel better soon.. I'm a gerd person .have had it for a long time. Trying to eliminate hpylori for the 3rd time now..still there.
I was on two rounds of protonix, the first time dint really work but I was also not dieting right, the 2nd time it worked much better cause I had a better diet. Still have heartburn but nothing like I used to. And I'm also able to swallow foods way better than I used too. It got so bad that i couldn't eat anything without drinking something with it, it sucked. Definitely get it checked out asap. The sooner the better.
I wish you well man, the symptoms and issues will subdue by Gods grace

And there are many more reason that stop you from actual learning in schools.
@@abhayagarwal5097 Yeah, I'd also argue highschool isn't the best place to expand your mind. Even when I was in school, before I had to leave for work and family problems, only a small portion of my knowledge came from school. In fact, me egressing from school to standard life has undoubtedly allowed me to integrate more knowledge by it being stuff I *choose* to learn. I essentially have my own curriculum on my own terms. No bounds, no sense of deadline nor a looming head telling me I must learn specifically what is in front of me.
Speaking of food and digestion. It'd be interesting to see a breakdown of what happens in your body when you eat spicy food.
Spicy food tricks your brain into thinking that your mouth is “on fire” - the brain gets the same signals as if it was actually on fire. When the Capsaicin gets into the nose your body tries to flush it out which is why you get a runny nose - you may also experience drooling and watery eyes. When the capsaicin (what makes spicy food spicy) gets into the stomach it stimulates the production of gastric mucus which temporarily speeds up metabolism. When your stomach works to digest the spicy food you may experience pain but it’s not causing actual damage.
Here’s is the whole process:
1. Capsaicin binds to pain receptors on your tongue.
2. The brain cools the body by sweating, salivating and producing mucus.
3. Pain receptors in the esophagus causes a burning sensation in the chest.
4. The irritated phrenic nerve may affect the lungs which causes hiccups.
5. Pain and cramping the stomach occurs.
6. The rate of digestion increases which causes diarrhea.
7. Perianal burning may occur.
Does that help?
@@DnArLw good points here. I wonder if the spiciness triggers anything in the stomach itself though
@@DnArLw So if i eat spicy food, i will loose weight more faster? since my metabolism has sped up
@@Xdetonando it doesn’t specially help with weight loss, you won’t lose weight by just eating spicy foods. However, as spicy food reduces appetite and increase energy expenditure it can help with weight loss but don’t use it as only one option. Does that help?
@@prapanthebachelorette6803 Hi, in the first paragraph I did answer this but I didn’t really make it clear 😂. So when the capsaicin enters the stomach sit produces gastric mucus which temporarily speeds up metabolism. Is that more clearer?
Important safety info: when diluting hydrochloric acid, always put the acid in water and never the water into acid!! The dissociation of H+ and Cl- ions in water is a highly exothermic reaction (it produces lots of heat) which can evaporate water if the water is in small quantity (when you just started pouring). If you pour the water in acid, this can bring hot acid droplets onto you! Be very careful and always take safety measures like gloves and goggles, like this gentleman here.
Great material, by the way! ;)
diluting hydrochloric acid isn't particularly exothermic. Also, always put the liquid with low heat capacity into the liquid with high heat capacity, i.e. when preparing 90% sulfuric acid from 96% put the water in the acid.
Good to know 👍
its the same with everything. even in cooking
@@Doping1234 sulfuric acid has higher heat capacity than water?

Fun fact, a nitrile glove is actually latex free. It protects against chemicals. Nitrile gloves are used alongside latex gloves in the medical field for those who are allergic to latex.

One issue with the meat in the stomach acid... when it’s in your stomach it is chewed and therefore has a much greater surface area. This will make meat of the same volume dissolve at a faster rate.
Also, he should try adding some pepsin to the solution.
That’s right.
Just casually saying a human stomach turned inside out is the best thing I've heard today snd nothing will top it.
Kenny Ford: What did the inside out stomach sound like?
He is actually teaching me what I had forgotten during chemistry class of my pharmacy school.
90% talk 9% gesture 1%practice
This absolutely makes sense! The stomach acid isn't designed to obliterate anything you eat. It's designed to break down the proteins in food and make your food easier to digest. If it obliterated your food, then that's counter productive because your food would be gone.
Edit: just got to the end and I literally just said what you said. LOL great video!
The guy actually said the acid STIMULATES the digestive enzymes that will digest the protein like pepsin.

As an Italian I’m always amazed to find out pretty much every name used in anatomy is in fact an Italian word some of them still used in modern Italian
That is because all names are from Latin and Italian is one of the Romance languages that derive from Latin...
@@thanoof the fact that they derive from Latin (which btw everybody knows) has absolutely nothing to do with what I was saying. Modern anatomy was consolidated during the reinassence and most of the terms were invented by Italians like Da Vinci ecc. Not Ancient Romans so…still amazed some common Italian words are being used in English anatomy.
@@lo5492 still latin, not Italian
@@IgorDPortu Looked it up again, you’re both right, that’s Latin not Italian. I was wrong 🙌🏻
Well, Latin is considered the language of Science. You can say similar things about other languages like; German is a language of command (Great for Dog/Pet training), English is a language of Trade (Culture Melding, Global Colonization and the Internet), ect.
One of the most scary things I have ever experienced, was being suddenly waken out of my sleep, taking deep gulps of air, feeling like I was being suffocated with this strong burning sensation in my upper chest. My initial thought was that I was suffocating somehow, and so I was literally *heaving* breaths trying to get it under control. Took about half a minute for me to realize just what had happened, when I noticed the taste -- stomach acid had crept up the esophagus and into the lower throat and the pain of it tricked me into thinking that there was something wrong with my lungs and my body responded by taking in huge breaths of air and also triggered the fight-or-flight reflexes as well as waking me out of sleep. Thankfully that has only happened to me like 2-3 times and the second time and beyond, I recovered quicker because I know exactly what it is now. The first time was damn scary, though.
Also, one more observation: you dropped the meat in, as one big chunk. This serves as an excellent demonstration of why you really need to chew food properly. Breaking it down into smaller pieces makes it easier to dissolve and break down (because breaking it into smaller pieces vastly increases the surface area being exposed to the acid). If you don't believe me, you can reproduce this effect with good ole ice. Get two ice cubes, smash the one into tiny bits and leave the other alone and let both melt. Note how the former is reduced to pure liquid much faster than the latter.
Wait so can this cause shortness of breath?
@@rambofirst2052 No. It just _feels_ like you have shortness of breath, but you really don't. It's your body overreacting to the pain in the esophagus.
Same happened to me then it stop once I started taking probiotics vitamins. I guess my stomach acid was high in acidic levels.
The first time I had a Charlie horse....
hi this video is great and I love this educational content .However, there is a wrong fact at 5:51 you said that the increase of acidity between ph 7 and ph2 is 50 times due to the fact that the difference between ph7 and ph6 is 10 fold but, the ph scale is logarithmic meaning that the difference between ph7 and ph2 is ten to the fifth power not ten times five. However I do not wish to criticise this channel as I love your content.
I was looking for someone to point this out, pH 2 actually 100,000x more acidic that pH 7
True😁
Pointing something like that out is good! Specially in a science channel, science is all about corrections and working together to perfect knowledge
Thought so. Good observation, I agree it should be mentioned as it is helpful.
Yeah pH is a logarithmic scale to the base 10.
Which means pH is the exponent to 10.
So going from 7 to 2 is 10^5 x increase. Or 100000x increase in acidity.
More appropriately, increase in H+ ion concentration.
I was so engrossed in this video. I enjoyed it so much. If I was his student I am sure biology would be my favourite subject.
i love how they get so serious when they are talking about anatomy, you can tell they love what they teach!
16:30 great video to show the importance of emphasizing chewing as part of the digestive process. Kids should see this experiment. Good job.
Thank you!
@@theanatomylab I read that as I hate you 😂 why??
The anatomy and physiology of the stomach has always fascinated me. It contains an acid with a pH so low, that without a thin lining of cells and mucous, the acid would eat through the organ itself. Seeing the effects of NSAIDS and how they inhibit this protective layer is a good common example of a stomach being eaten by its own acid.
I've been browsing RUclips for 14 years. You are the first video that i ever liked. It's clear why your in the medical field. Your curiosity to learn is apparent.

For those with frequent heartburn, I would recommend seeing a GI doctor to get it under control and prevent damage to the esophagus. I was diagnosed with Barrett's Esophagus this year at age 29. In my case, for the rest of my life I have to take a type of medication called a PPI (proton pump inhibitor) that reduces the amount of stomach acid produced. Although a small percentage of Barrett's patients get cancer, it is still a higher risk. Fortunately, there are procedures that can be done to lower the likelihood that it progresses to cancer.

For those interested. ,The Stomach acid still goes down further the digestive system, in the Duodenum, thanks to the Pancreas and some cells of its own, the ph of the acid increases, making it "non-lethal", since none of the other digestive organs have the functions to increase the ph, nor the "mucus" to deal with it for too long (note they all have mucus but different kinds).
