I love how thorough the explanation is, as well as how you get people to engage and understand the material. My teacher heart found this very satisfying :)
omg so did I lol. I woke up at 3 am and for some reason asked myself do gills separate the oxygen from hydrogen? couldn't get back to sleep till I found out. writing this now I realize if you have a fish tank and don't circulate the water, putting more o2 in, the fish will suffocate despite there being of water. I'm 28 and it took me 2 hours to realize that smh.
heck yea some of the coolest things I've learned I've learned in the middle of the night either after a weird dream, after heavy drinking, or just random thoughts while trying to get to sleep lol
Thank you for this! Im in Animal Physiology and my teacher tried giving us a similar example but his example confused me more.. You explained it very well!! Thanks again!
i am so lucky to have found ur channel. Your videos are exactly what I was lookin for according to my syllabus and calibre, sometimes i become so obtuse in class, but ur videos make me realize m not a dimwit
Omg thank you SO much. I have my animal physiology exam later and I know that water-breathing animals mostly use countercurrent but I didn't know the mechanism, until now. You're the best :)
Thnks for yor vids. Explained extremely well. I ve been subbed for about 2 months now. The cellular repiration and photosynthesis vids were where I started. They were spot on. Only neg I have for ur vids is the volume seems lower than most videos. Besides that they are awesome and very helpful.
Woah! This helped me so much :) I will be having biology final with a whole gas exchange theme and this really helped, because i have to remember so many things and this was a little bit confusing to me :D My teacher would be mad if she knew that i understood this in English and couldn't understand it in my mother language ;DD
You are a really good teacher! Could you maybe also do a video on countercurrent exchange in kidneys and for even heat in mammals? Thanks for the video! You really helped me out :)
Hi i just watched your video and I was wondering whether you can provide an easier/concise definition of what the counter current exchange is. Am having my biology exam on Monday, which is tomorrow.
The blood and water don't mix. The blood stays in the capillaries and absorbs oxygen from the water through the walls of the capillaries. It's a bit like the engine cooling system in your car radiator.
One thing I don't quite get here. I don't see why the examples are that different with regards to the "final product". They are both resulting in 20ppm of oxygen diffusing into the vessels of the gills. With the concurrent flow surely diffusion is initially faster then slows as equilibrium is met compared with the slow and steady counter current system.
Google Plex I'm not that smart but if you study how an aquarium works you might find an answer... I mean you need to VENTILATE an aquarium in order for the water to be mixed with oxygen BUBBLES. I belive it's the same in every water enviroment. The gils are functioning just like the lungs, the difference between gils and lungs consists in the fact that the lungs can process a higher quantity of oxygen and the gils can't do that, but when the air bubble from the water meets the gils the oxygen from the bubble is transfered to the blood.
I still don't understand why the water has only 80ppm O2 before the counter current blood even reached the water. Shouldn't the water still have 100ppm O2 before the blood came? Where did the 20ppm O2 go, when there was no contact with the blood before? I am not sure if someone understands what I mean. But if somebody does, I would appreciate an explanation.
Great video. I'd love to use it for my marine science class presentation. I also teach Human A&P and will look for your rete mirable and Loop of Henle videos!
Couldn’t you make a diving rig that , instead of supplying air it pulled the divers blood into a sterile machine that brought the blood into contact with the water to transfer oxygen.. then filter back into the body… the diver would not need to breath but probably should breath a inert gas but all oxygen exchange would come from the blood
I've been confused with this concept for years, but you concluded everything! Thank you so much!
Glad it was helpful!
I love how thorough the explanation is, as well as how you get people to engage and understand the material. My teacher heart found this very satisfying :)
i don't why i looked for this video in the middle of the night for no reason , but i m glad that i understand it :')

that s a cool thing to know i guess :') wierd late night thoughts rule !
heck yea some of the coolest things I've learned I've learned in the middle of the night either after a weird dream, after heavy drinking, or just random thoughts while trying to get to sleep lol
hahaha saame !!
eya ayadi me too
I woke up this morning and my first thought was, "How do gills work?". Thanks for clarifying.
Nice brain
Thank you from an old guy who has not completely understood this until now. Great work!
Thank you for this! Im in Animal Physiology and my teacher tried giving us a similar example but his example confused me more.. You explained it very well!! Thanks again!
I have a tiny class of two 7th grade students... who are pretty sharp! This will be great for them!!! thanks very much!!!!
This really helped with my study for an upcoming test, thanks
i am so lucky to have found ur channel. Your videos are exactly what I was lookin for according to my syllabus and calibre, sometimes i become so obtuse in class, but ur videos make me realize m not a dimwit
FOR SERIOUS STUDENTS, IT'S BEST VIDEO!
This makes so much sense. Thank you! My textbook didn't explain it well at all.
Extremely helpful. Thanks a lot.
All these people understanding it and I'm sitting here before my 50% exam hella confused
How did it go?
@@hihi-bh3krhope she tells us soon
You X-ray image just killed me.
great presentation just like a meditation.....
Well explained! Thanks for letting me understand the whole thing!
I usually do not exalt someone and this is Awesome video. Many thanks.
You're a brilliant teacher
Thank you, this will help me on my exam later today!
Omg thank you SO much. I have my animal physiology exam later and I know that water-breathing animals mostly use countercurrent but I didn't know the mechanism, until now. You're the best :)
Very understanding video . nice presentation
Great video! Exactly what i needed to know for my exam👍
amazing explanation, very clear, cut and clean. This is a brilliant system, so impressed !
Thnks for yor vids. Explained extremely well. I ve been subbed for about 2 months now. The cellular repiration and photosynthesis vids were where I started. They were spot on. Only neg I have for ur vids is the volume seems lower than most videos. Besides that they are awesome and very helpful.
This helped a great deal, thank you.
Explanation is very inspiring an intelligible.
great explanation i didnt understand the countercurrent bit but now i do!
u explained this so well thank u! my teacher just said something about a fish and the gills and drew a crazy pic. very helpful!
Great information, thanks. I wonder if that gradient idea is also functional in itself, since energy never wants to stop.
Really good explanation, thank you! :D
wow you're voice is so soothing! Thanks for the well explained video.
Great video!
I just had one question-does the carbon dioxide gradient work in the same countercurrent fashion as the oxygen gradient?
yes
Woah! This helped me so much :) I will be having biology final with a whole gas exchange theme and this really helped, because i have to remember so many things and this was a little bit confusing to me :D My teacher would be mad if she knew that i understood this in English and couldn't understand it in my mother language ;DD
amazing work buddy
does the countner current exchange increase the amount of oxygen that is diffused into the blood?
Yay I got it! THANK YOU SO MUCH!
You are a really good teacher! Could you maybe also do a video on countercurrent exchange in kidneys and for even heat in mammals? Thanks for the video! You really helped me out :)
Can we make artificial gills ?
Is it changing molecular H2O or is there 02 gas in the water
There is dissolved O2 in the water
8 year question: what are the membranes, enzymes, cells, etc. Used in the gills?
Nice video....I understood 👍
ASMR warning -- kH
Amazing Video! I have an exam tomorrow and needed a refresher and it served me well :D
i used this for a presetation and it worked out well !
Surprisingly helpful.
sir, in this video, you didnt explain as to how and by what mechanism is oxygen separated from the water inside the gills ????
Hi i just watched your video and I was wondering whether you can provide an easier/concise definition of what the counter current exchange is. Am having my biology exam on Monday, which is tomorrow.
best explanation. Straight forward !
How does gill filter out bacteria and toxic chemicals
Love your video.. but can fish gills be manufactured for human use?
Thank you so much! You are an angel!
I don’t get how the blood mixes with the water, it’s inside the vessel right?
The blood and water don't mix. The blood stays in the capillaries and absorbs oxygen from the water through the walls of the capillaries. It's a bit like the engine cooling system in your car radiator.

This 8ne was helpful.......I understood it!!!!😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁
Thank you for the great video!
thanks to you I understand how it works now
This was great! I was quite confused with concepts until I watched this video
It also moves the blood with the highest oxygen level through the head/brain first.
thanks this helped me with my science project what i will be doing is puting a fish in defferent water tempitures like cold and warm
Thanks, I woke up at 5 and had this random question
the teachers voice is different.
lol
Great explanation! :)
What is the difference between salt and fresh water
thank you for this explanation!
This helped me so much
I thought that water goes in through the mouth and out through the slits at either side of the body.
Ur a bio teaching god
Oh my god the whisper came into my headphones at the beginning and it scared meeee why does the voice sound likke that
Emma Wallisch òiid8sunek4udu2k9m
I have my zoology final tomorrow and this really helped :)
but sir you didnt talk about the process of ruardation which is the most important mechanism in fishes.
Do you have a video on how axolotl gills work?
That's great sir. Superb..
he is spitting facts in this video
Understood it better than before
what is the biology in the fish gill that allows it to absorb oxygen?
Google Plex I'm not that smart but if you study how an aquarium works you might find an answer... I mean you need to VENTILATE an aquarium in order for the water to be mixed with oxygen BUBBLES. I belive it's the same in every water enviroment.

I live your voice.
Why can't my teacher be as good as you!?!?!
Very helpful explanation, thank you!!!!
I still don't understand why the water has only 80ppm O2 before the counter current blood even reached the water. Shouldn't the water still have 100ppm O2 before the blood came? Where did the 20ppm O2 go, when there was no contact with the blood before? I am not sure if someone understands what I mean. But if somebody does, I would appreciate an explanation.
can some 1 make a mask using fish gills or it is impossible ?
2:15 bold of you to assume I chose B as the correct option
I'm Satisfied! 😇
Great video. Thanks!
Great video. I'd love to use it for my marine science class presentation.
I also teach Human A&P and will look for your rete mirable and Loop of Henle videos!
Knowing the answer is one thing, understanding the answer is other -craig savage
helped so much! Thanks :D
Thanks sir.
very helpful video
great video, thanks for putting this together
Are u related to John savage
Help please Four reasons why the gills are highly vascularised
0:45 What an xray
Nice video 🐠
thanks, this really helped!
Savage
So confused still, thanks though.
Brilliant video! do you have a email if I have any questions?
Great video
please make a video of the structure of a gill
Couldn’t you make a diving rig that , instead of supplying air it pulled the divers blood into a sterile machine that brought the blood into contact with the water to transfer oxygen.. then filter back into the body… the diver would not need to breath but probably should breath a inert gas but all oxygen exchange would come from the blood
