Urinary System, Part 1: Crash Course Anatomy & Physiology #38
HTML-код
- Опубликовано: 26 июл 2024
- Even though you probably don't choose to spend a lot of time thinking about it, your pee is kind of a big deal. Today we're talking about the anatomy of your urinary system, and how your kidneys filter metabolic waste and balance salt and water concentrations in the blood. We'll cover how nephrons use glomerular filtration, tubular reabsorption, and tubular secretion to reabsorb water and nutrients back into the blood, and make urine with the leftovers.

This helped more than a 55min anatomy lecture at a university- thank you
bit of a mood ngl
Dude if you were my professor, I would be a doctor by now. Your way of teaching just resonates with me so much. So easy to absorb
This video makes me realize that I have to stop making jokes about selling my kidneys.
Giselle Bourgoing Is
nah u could actually still sell one of ur kidneys and still live normally with no complications.
@@Tentenn144 You should probably still keep it if you don't need to get rid of it. Because if that one goes down....
sell your hair instead.
Hi I have question . what is the purpose of the motion of water out of the ascending limp into the medulla . is it to move back to the blood or is it for urination . I really do not get it
This guy makes learning Biology soooo much fun!!! THANK YOU !!
Ryan R thanks for sharing
Ryan R your profile picture makes me happy. I don't even know why.
P.S. your totally right they make it alot of to learn :)
No way boring sir
I just wanted to say that I was able to get an A on my Human AP 2 exam by watching your videos for further understanding of my notes and power points! Thanks a bunch.
I would lilek to be a emt
Thanks a lot
And now you're a doctor!!
So what's your profession now? Kinda curious
Hi pls help me out . what is the purpose of the motion of water out of the medulla . is it for urination or its moved back into the blood
It's fascinating to imagine how our organisms manage all of these complex processes, and how they came to be in the first place.
+DaCamponTwee Organs.
The kidneys of many other organisms do much the same thing.
wholeNwon Obviously.
+DaCamponTwee something something god created stuff, evolution is a lie etc..
Netsuko Yoshikawa I believe in evolution and I'm an atheist. IDK why people are jumping to these conclusions.
DaCamponTwee I was actually just making a joke as I was expecting someone to jump in and talk about "God" and "the creation of life" and such.

Didnt expect to learn how to clean out a refrigerator but here I am.
I’ve watched this entire course too to bottom for my A&P I and II class. It even goes in order by my book. THANK U CRASH COURSE! This channel has helped me on my test like no body’s business
I used to find crash course videos also too fast. I recommend to learn it from the textbook or whatever professor says. And then watch a video super fast for the overview, to refresh and see if you learned it good
Marina Zh
Marina Zh same
Highly agree!!
you can regulate the speed you know?
Actually I feel that watching the videos will give you a good general idea of what to expect in a more detailed textbook. I have a bunch of slides for a class and it works best this way (for me at least).
i am currently in nursing school and this video helped a lot with the current topic of renal failur! Thankyou very much😊
I am currently in nursing school and this video helped a lot with the current topic of renal failure! Is there any chance that you all are considering creating a pathophysiology course??? These videos have helped me a lot over the last few years and the way that you guys present information is amazing! Thanks, guys!
Yes he talks too fast but that's the unique part of it. He holds your attention, great job. Thank you😊
I have to say, when I saw this video in my subscriptions, I was a little pissed.
*badum tssss*
+PotatoesAreGood :3 You mean *badum psssss*
+Dan Heidel I laughed so hard I peed myself.
+Jennie Kerfuffle really?
guest guest You better peelieve it.
Crash Course, I can’t thank you enough for making these videos. Anatomy and physiology are prerequisite classes for me and I don’t even know what I’d do without your videos. These videos give me a great basis on each topic we tackle and it helps immensely with understanding the basics. Thank you!
Wow 20% now I respect my kidneys more then before, thanks kidneys!
This helped me a lot at school
Your explanation as a great starting point presentation and could actually be given at every medical, nursing school…and it would be great for college and high school…because of how you describe pretty much everything…it makes a great overview…you vide many key definitions, anatomy, and functional relationships. Really great!
This series is a life saver! I'm able to watch an episode after studying to get a nice little summary of what material was just covered and thankfully you and my professor use the same terms!!! You guys are so wonderful!
Perfect timing! I am teaching the Urinary System tomorrow! Can't wait until Part 2 is available!
This is helping so much for my medical terminology midterm tomorrow. Thank you Hank!
First, I came here to learn about my kidneys, then I was fascinated by how fast a human can talk and then did he memorize all that information cause I didn't.
No, he reads according to a script prepared before the AP episode which was of course guided by their consultant Dr Brandon Jackson.
Starting my new job at a urology clinic next month and even after years of schooling it’s nice to review/refresh the memory with videos like this one.
This channel is THE best. It is still helping me to this day even though this was posted years ago, thanks
Nephrons, eh? *imagines many tiny Zac Efrons inside kidneys*
LOL Zac Nefron
WhO iS zAc NeFrOn??😂 but seriously, who is ZAc nefron?
I spend so much time cracking up at this guy that I have to keep rewinding to learn all the bits! Thank you for your helpful and hilarious ways of teaching biology :))))
thank you so much crash course for bringing all the info that i'm being bombarded with in A&P and making it easier to understand!! it makes putting all the details together much easier!
Love the videos, they are really helping me understand my anatomy class better because I have been having a hard time focusing in lectures.
I really thank you for making this learning video. In this video I can relearn the basics of discussing anatomy which in my opinion is quite difficult. you guys are awesome Crash Course, thank you!
Shoot I gotta rewatch this whole video because I was scrolling through the punny comments. Now I'm pissed
Rebecca M better pissed off than pissed on xD
Me toooooo
You are amazing
Watching these videos never fail to help me further understand my readings! Thank you!!!
This is such an informative yet fun approach on a way to learn about the urinary system! You've earned yourself another subscriber!
Thanks to whoever translated this to Arabic ~ Thank you so much 💓💓💓
After this course is over, I would absolutly love to see a zoology course.
CrashCrourse ! Thank u so much ! I was reading and reading in my native language book for hours until i realised that i didnt understand anything of what i just read. After this and many of your videos, I've learnd the same stuff that is written in my book much easier.. so just wanted to say thank you and keep making videos ! sorry for some bad english =D
amazing man...just thank you for your knowledge, passion, simplicity, and thoroughness!
Awesome channel, helps greatly with my P&A class. Thanks for giving the kidney a Cubs cap...a World Series champions Chicago Cubs cap! GO CUBS GO!
You are really good at what you do thank you for making Anatomy Fun!!!
I"m on exchange in Argentina right now and I'm learning about the kidney. Well everything is in Spanish and I have absolutely no idea whats going on in biology class ever and it sucks. I have a big quiz tomorrow and next week is the chapter test and this really helped me understand what is going on. I can understand about 35% of whats going on in the class in Spanish and this video really helped me piece together the extra 65%. I've watched this specific video about 3 times and took notes on this, I cannot tell you guys how much you have helped me and my studying abroad life. Thank you so much! You and John Green are helping me pass my classes one video at a time. Also, my sophomore honors world history teacher would religiously show us the Crash Course videos in her class. Those videos also helped us pass her class and I want to thank you guys for that!
Still gracefully getting me through A&P, thank you!
If I could take your brain into my exam next week.
Just have to thank you guys for these videos. They teach SO MUCH. I recently realized I know more about internal anatomy now than my PT mom does.
Thanks for all the knowledge! Keep up the good work! :D
Thank you so much!!!!! These videos are so fun to watch and really help me with studying!
I used to watch these for fun. I've now had to come back and watch and LEARN them again as I'm doing nursing and lecturer can't teach?? Thanks so soooo much. Love you guys.
Getting ready for my interview with a nephrology clinic (because I forgot everything like a dummy from my med classes 🤦♀️). This vid is super helpful and hopefully I get the job!
Its amazing how even though he is reading it sounds like he knows what he is reading.
Great explanations. I just learned about the kidney in class. Facinating!
all of your anatomy videos are the reason I'm passing anatomy class. These videos are amazing and so helpful. Thanks to you I will finish school and be a massage therapist.
I pavloved myself into feeling stressed and tired whenever the intro starts playing. The crash courses I watched in ×2 speed on my way to school have definitely left me something to remember for the rest of my life... not biology knowledge, that's for sure 😅
yaaass we're having a test about this soon! This really helped!
I came back to this crash course after reading various books. Now it makes more sense to me. It's also a helpful reference for my teaching demo.
this was so helpful! I already had a pretty good understanding but this really helped me totally understand the basics! quick review!
You have to have a “fast” mind to keep up with his fast presentation.
They have to keep them under a certain time or people will become uninterested. You can always slow down the playback speed if you need to listen carefully.
OMHFG WATCH IT AT 0.5X SPEED HAHAHHA ITS HILARIOUS
DRUNK SCIENCE!!!!!!!!
heck ya😆😆😂😂😂
this guy makes learning biology so much fun! thankyouuuu
thank you, these videos and pictures really help to understand how the anatomy of the urinary system works
i. love. crash. course.
I'm here for my TEAS test lol
i always watch your videos before i have a biology test. they help me so much because i can see what my teacher has explained to me. Thankyou :)
This was inserted in to my Biology class reading and l love it. Quick and clear explanation and super easy to understand 😍
So, I am a procrastinating nursing student that has left the revision for my applied physiology exam very, very, very late! It is safe to say, if I pass which I probably will (just about), thanks will be to videos like this and only minimally down to the lectures provided by my university :0
Crash course is so underrated, wish more schools would incorporate videos like this
Thanks for this amazing video!!!! This is AWESOME!! I almost watch it three times. Although you speak so fast, your pronunciation and accent are so good that I can understand!!
Love your fast no-nonsense presentation.
This man is amazing. Always excited to teach. Literally has saved my life so many times😂❤️
I'm hoping the next part covers what happens when there's either too much water or not enough water during the problematic section.
Quality video geared towards actual learning! Thank you much!
Thank you for this video about urinary system part 1, the content is very useful. Can be used as medium of learning for me
The tubular system looks like a great motorcycle race track.
nice and twisty with two speed lanes.
Yay 🎉 I have been looking forward to watching this, but now I have to wait a whole week to see another 😔
#Crashcourseproblems
***** Report and block them.
++CrashCourse WARNING STUPID SCAMMING FAKE ALERT
+Legionare Lets Plays (LLP) You got me to search Twitter for #Crashcourseproblems.
the video explains the location, parts of the kidney in more detail, quite understandable, clear explanation
I’m glad this channel exists. Makes college a little easier.
I just realized that this is my last year of highschool
I like how this dude literally explained how the urinary system works faster then any of my 6th and 7th grade teachers
thanks for the making video. i'm being bombarded with in A&P and making it easier to understand, it makes putting all the details together much easier
Wonderful! Congratulations on a great job! One suggestion is to provide PDF flashcards about the content. It Wil certainly help us to fix them!
I'm a fan of this guy
Do a video about Kidney Stones please!
Does Hank do pathology? Kidney stones are a terrific thing to learn, but it'd require at least 5 mins on its own.
+XFreeStyleZX Ooh ooh, CrashCourse Pathology!
+SubscribeToSyndicate That'd be really cool, but risky to make. A lot of not-so-bright people might start diagnosing themselves and that could be a problem. Although just learning about pathology from a scientific perspective would be fantastic. A lot to learn, too!
+SubscribeToSyndicate I know, right?!
+XFreeStyleZX I am so sick of catering to the bottom 5%. No one seems to get any attention in the country unless they are willfully ignorant. We really need to stop with the whole excuse that people are "not ready" or "not equipped" to handle information.
Glad to know this channel exist, Thank You!
I have a biology report due tomorrow and this has saved MY life! THANK YOU!!!!
You’re amine one, Mr. Grinch
I feel like to go peep after watch this video
This is such a well done video! Thanks for the help!
Love your work! This was super helpful!
Seriously? Who disliked this? Probably, Bear Gryils.

+CDR. Javik lol good one!
Why? What he did was legit. You can distill urine to get pure water back.
+greg77389 This is arguable. It really depends on the pH balance of your urine. If you are passing a lot of water through your renal system and your urine comes out light/transparently clear, you can simply drink your urine and get most of the water released in it back into your body. Over time however your urine will be a higher concentration of ammonia and other things your body is trying to get rid of. At that point, your urine will be too far gone like ocean water.
Urine is your body's filtering processes. If you have overabundance of water in your body, you're peeing out water. If you slowly absorb all the water that you can, your urine will sooner or later no longer be useable for a water source. At most it'll probably last you a several urination processes for your urine to start doing more damage than immediate survival.
laxjoh CDR. Javik like ocean water, urine can be desalinated and filtered in order to remove substances that cause the acidic pH. The methods used for filtration involve several different sediments, as well as charcoal. (Not the same for desalination) Although, I agree regarding just drinking urine- the substances would absolutely become more concentrated if not filtered effectively.
bro bring this guy back please
Love this course on crash course! You are pretty freaking a-okay, Hank!
Hank your videos made me love biology THANK YOU
0:00 keep repeating it lol
jajaja x2
This video worth 5 points in the IGCSE Examination Biology paper 42 that I've taken today (28th October 2016)
This is amazing! For Funeral Services ( embalming) , this is great before doing my exam tomorrow. Thank You!!
wow thank you this video has added to my insight about the urinary system
8:00
Isn't the ascending limb impermeable to water?
man you're soooo good, I like your channel a lot but man you talk too fast !
you're the best :)
He goes like he is a robot . 😂😑
But i think he is reading from a board while they are filming him.
Yaser alhassan u can slow the speed down
Thanks to you sir, today I managed to pass my exams and get into Medicine! You are amazing!
I so wish uni lecturers taught like this. I LOL sometimes during these lessons. You make the urinary system not so scary after all!
It would be great if it weren't so fast. It's like watching Alton Brown on the Food Network. Slow down. Great info, though.
Thanks for taking my booooooring text book's description and turning it into something I can follow. Online courses can be rough from the dry material, thank god for youtube!
I learned alot from this video. Thank you, eve though you talk a bit fast, I like that you are like talking to me instead of reading a list.
fantastic! one of the best episodes of crashcourse
