Urinary System, Part 1: Crash Course Anatomy & Physiology #38

[@SquatSimp]

This helped more than a 55min anatomy lecture at a university- thank you

[@aaaxel]

bit of a mood ngl

[@alexabourg]

This video makes me realize that I have to stop making jokes about selling my kidneys.

[@jalaldarwish8053]

Giselle Bourgoing Is

[@Tentenn144]

nah u could actually still sell one of ur kidneys and still live normally with no complications.

[@queensheba9792]

@@Tentenn144 You should probably still keep it if you don't need to get rid of it. Because if that one goes down....

[@betterlucknexttime7534]

sell your hair instead.

[@leralto-khutjokarabokapa1646]

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

[@Catlover955.]

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

[@jameswray50]

It's fascinating to imagine how our organisms manage all of these complex processes, and how they came to be in the first place.

[@wholeNwon]

+DaCamponTwee Organs. The kidneys of many other organisms do much the same thing.

[@jameswray50]

wholeNwon Obviously.

[@Netsuko]

+DaCamponTwee something something god created stuff, evolution is a lie etc..

[@jameswray50]

Netsuko Yoshikawa I believe in evolution and I'm an atheist. IDK why people are jumping to these conclusions.

[@Netsuko]

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.

[@susantheho]

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.

[@caitlynmayrandcaitlynmayra5596]

I would lilek to be a emt

[@anjalip9077]

Thanks a lot

[@brodieryan9767]

And now you're a doctor!!

[@khanmc8435]

So what's your profession now? Kinda curious

[@leralto-khutjokarabokapa1646]

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

[@northvanman1283]

This guy makes learning Biology soooo much fun!!! THANK YOU !!

[@choochney]

Ryan R thanks for sharing

[@pearlcorder391]

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 :)

[@guglemalik7148]

No way boring sir

[@americanbee]

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

[@romainroulier8971]

[@nolans5906]

Marina Zh same

[@Stothep15]

Highly agree!!

[@santoelectron]

you can regulate the speed you know?

[@marcoperez-maccollum4688]

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).

[@aperson22222]

I have to say, when I saw this video in my subscriptions, I was a little pissed.

[@JourneyToJourneyman]

*badum tssss*

[@macielynn1072]

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

[@wecantbefriends1660]

Didnt expect to learn how to clean out a refrigerator but here I am.

[@ikaseptiyani9172]

i am currently in nursing school and this video helped a lot with the current topic of renal failur! Thankyou very much😊

[@jamiekuhn8258]

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!

[@kikitsar295]

Yes he talks too fast but that's the unique part of it. He holds your attention, great job. Thank you😊

[@mckrokonus]

Wow 20% now I respect my kidneys more then before, thanks kidneys!

[@rmb.artistry]

Shoot I gotta rewatch this whole video because I was scrolling through the punny comments. Now I'm pissed

[@camobanana1]

[@ruthawallace3702]

You are amazing

[@fsdx416]

LOL Zac Nefron

[@juanitaw156]

WhO iS zAc NeFrOn??😂 but seriously, who is ZAc nefron?

[@yasmeeny1168]

This helped me a lot at school

[@shyandagger4135]

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!

[@David-kk4dr]

You have to have a “fast” mind to keep up with his fast presentation.

[@milkman9509]

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.

[@SayaCeline]

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!

[@laumay7364]

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.

[@aidendaniel9812]

No, he reads according to a script prepared before the AP episode which was of course guided by their consultant Dr Brandon Jackson.

[@EMedNation]

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!

[@peepeevs]

After this course is over, I would absolutly love to see a zoology course.

[@watchlovestanexo]

Thanks to whoever translated this to Arabic ~ Thank you so much 💓💓💓

[@MichaelCordero]

I’m glad this channel exists. Makes college a little easier.

[@marcusroy8185]

Its amazing how even though he is reading it sounds like he knows what he is reading.

[@Maggiemae33]

Still gracefully getting me through A&P, thank you!

[@adamgoulding4702]

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

[@Emma-vb7of]

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.

[@jessieevans7600]

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 :))))

[@stellabrimble2047]

I so wish uni lecturers taught like this. I LOL sometimes during these lessons. You make the urinary system not so scary after all!

[@BeckyMeetsWorld]

This is helping so much for my medical terminology midterm tomorrow. Thank you Hank!

[@vrillamelia]

this guy makes learning biology so much fun! thankyouuuu

[@virginiafulivai2228]

If I could take your brain into my exam next week.

[@spookyspacewhale1532]

Just wanted to say thank you! My A+P exam is tomorrow and i just couldn't wrap my head around this but now I get it!! Second year vet med here i comeeee :)

[@milkman9509]

Crash course is so underrated, wish more schools would incorporate videos like this

[@Nwordscissorhands1738]

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.

[@Legboy1129]

Seriously? Who disliked this? Probably, Bear Gryils.

[@Legboy1129]

***** Man Vs Wild.

[@ConradJD777]

+CDR. Javik lol good one!

[@greg77389]

Why? What he did was legit. You can distill urine to get pure water back.

[@laxjoh]

+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.

[@nataliejane8310]

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.

[@Fitzrovialitter]

Love your fast no-nonsense presentation.

[@emberstone1991]

You are really good at what you do thank you for making Anatomy Fun!!!

[@hannahtunks411]

Thanks Hank, hope I remember this during my exam

[@safirahfurqani5341]

i really like this video, but you are talking too fast

[@alien2rulz]

change the speed of the video, and add the captions

[@Tensi1126]

how can i do that!

[@vivecawang7491]

omg D.O 😅

[@tanishpriyadarshan317]

i recommend watching it once then watching it again with 0.5 speed

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!

[@samuelruizgomez2976]

This channel is THE best. It is still helping me to this day even though this was posted years ago, thanks

[@MissCutiePie20]

Do a video about Kidney Stones please!

[@XFreeStyleZX]

Does Hank do pathology? Kidney stones are a terrific thing to learn, but it'd require at least 5 mins on its own.

[@SusanWojcucki]

+XFreeStyleZX Ooh ooh, CrashCourse Pathology!

[@XFreeStyleZX]

+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!

[@TaiChiKnees]

+SubscribeToSyndicate I know, right?!

[@stephanieareson]

+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.

[@ayiee]

online classes have been so hard. thank you for this

[@sighko05]

I'm hoping the next part covers what happens when there's either too much water or not enough water during the problematic section.

[@emilyduncan3267]

I think I've watched this about 54 times. Crash Course guy, I love you

[@anisaazhari7464]

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!

[@faizhaaura7621]

the video explains the location, parts of the kidney in more detail, quite understandable, clear explanation

[@richardaversa7128]

The structure shown for urea (2:40) is "incorrect", there should be no little white ball up top (no H on the O, as it is a carbonyl functional group and not a hydroxyl). Just a little thing that would bother a chemist but it has no effect on the merit of this great video.

[@StrongMed]

Good catch!

[@zoekempe7474]

[@anotherelaaa]

video ini bagus dan mudah dimengerti karna didalam video ini terdapat penjelasan & gambar tentang semua proses sistem urine yg membuat pelajaran ini jadi seruuuu, thank you

[@miguelsolorzano6707]

i. love. crash. course.

[@subtleillusions]

I love your videos! One minor correction - the vasa recta is not the same thing as peritubular capillaries. The peritubular capillaries are associated with the PCT & DCT, and the vasa recta is associated with the Loop of Henle.

[@lagoonroom4600]

Yay 🎉 I have been looking forward to watching this, but now I have to wait a whole week to see another 😔

[@fnfjan]

Tiny correction, the Vasa recta is NOT another name for peritubular capillaries. Vasa recta are the transverse vessels that supply the tubules of MEDULLARY nephrons, in contrast to peritubular capillaries which are vessels that supply the tubules of the CORTICAL nephrons. But a lot of times are used interchangeably.

[@bigoljoe1829]

+Frank Nasrawistien I don't know why but comments like this irritate me so damn much but *fuck*!.. You have a "correction" you feel the need to issue, but then at the end acknowledge the terms *are* used interchangeably? So there was no *need* for your correction other than that you wanted to show people how smart you are? Or what? What the fuck is your damn problem?

[@Telamon8]

+BigolJoe To be fair, a lot of people use "you're" and "your" interchangeably, but that doesn't mean that they're right.

[@fnfjan]

+BigolJoe I don't have a problem, it seems that you are the one that has a problem, and why use profanity?? I made a simple comment for those who are interested, the terms refer to relatively different things, using them interchangeably is a misconception, thus making it inaccurate to use them interchangeably. I just don't understand the point of your comment, it was just a tip for those who are interested, if you found it helpful, good! if not, then just move on with your life.

[@cortster12]

+Frank Nasrawistien And then you go on and type out 'u' and 'r' like an absolute idiot. If you are trying to sound smart, stop shortening your words like a 13 year old teenage girl. It's a word crime.

[@wholeNwon]

+BigolJoe Obviously, when "people" use them interchangeably, they are doing so incorrectly. It's like the stupid people who don't know the difference between there and they're or their. Or discreet and discrete, etc.

[@oliviaenriquez8232]

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!

What are your thoughts on teachers saying "no" to student's ASKING PERMISSION to use the restroom?

[@Romanticoutlaw]

if you're lucky enough to be a female student past puberty and phrase it as "female issue", even if you just have to pee, most teachers will let you go so you don't get a biohazard all over the chair. But it is bs that something like that would be refused; I have a young cousin who had diharrea in class and the teacher refused to let her call her parents or go home because the teacher thought it was an attention thing. Pretty messed up.

[@CariBaez]

just go. and if you get in trouble, tell them to really have to go. sometimes they think you are kidding,n

[@mckenna8663]

Because usually it has nothing to do with needing to GO... just a want to get out. And those who pull that are the very ones who NEED to be IN the classroom. - That said, more and more (because of issues and threatened legal action) teachers are being told that they MUST let students go when they need to. BUT... my professors are now saying...if you need to go during a test, that's fine - but the test is then over for you. (Meaning - you can't pee until you're done with the test)
