Who needs a lecturer when you have Hank?

[@luxurious0346]

I do, and I want Hank to be my lecturer

[@sudhamshusuri1844]

I know I don't

[@hogrider2171]

Hank gives lectures

[@alondraarellano1072]

My final in Anatomy 2 is on the urinary system and my professor really rushed the lectures on it so as always I came to crash course for help and as ALWAYS I was saved. I thought I hated this system but now (as with all the other systems I thought I hated at first, yes endocrine, I'm looking at you) I think its really cool and that's all thanks to crash course. So thank you for existing and for helping me make it to the next step in my medical career. Nursing school here I come !

[@kieranrobo]

He got a haircut

[@jensharald9091]

Thought his hair was awful last episode and BOOM

[@shantyjaison1663]

Guess so

[@ScareSans]

@Jens Harald his hair is perfectly fine, thank you very much! >:[

[@Its.Desmond]

Came to say that

[@lordsibiya9351]

Respect the drip Kieran

[@DarlaBaltazar]

I spent lots of hours with you today, Hank. I deeply appreciate all of the knowledge you generously share.

[@sabreena1852]

Thank you Crash Course for existing and saving my semester! I find it amazing that you do so much just to help students understand concepts, asking for nothing in return. Thank you again!

[@benrosenthal5275]

well im pretty sure he makes money doing this. but hank is a pretty dope dude regardless

[@maxvillanueva3629]

I appreciated the swinging male representation of the urinary tract at 5:32.

[@bradleyh4532]

swiiingiiiinnn iiiin the wiiiind

[@jacoblee6079]

It's accurate anatomy

[@adrianamunguia9887]

XD

[@palaksharma1777]

I wish this video talked about the hormonal influences in much more detail. Like more than just a note about the renin-aldosterone-ADH mechanism. But great series though.

[@jameswray50]

I love these videos. Living beings are so complex and fascinating and sometimes a little scary.

[@benzxr2]

+DaCamponTwee Yeah, if only we could be more like them.

[@cutie6838]

Indeed. Thanks to God that is so.

[@vuciguraj]

+DaCamponTwee There are many components to studying anatomy. One resource I discovered which successfully combines these is the Anatomy Blueprint Pro (google it if you're interested) without a doubt the most useful course i've heard of. Check out this awesome website.

[@gints2766]

Meanwhile I'm here because I don't pay attention in class

[@nathan.3701]

especially the eye video... *shivers*

[@Finkelfunk]

Tasting urine used to be quite common up into the early 21 century. It was an easy method to see if someone has diabetes or not. If they do, the urinary system will do anything to remove the glucose in the blood, resulting in the patient peeing an awful lot and the urine tasting sweet.

[@mandydax]

I had a stomach surgery on Friday, and of course the nurses track my urination while I'm recovering. My high score was 800 ml.

[@BBBuilds12]

If you quit peeing you're in trouble.(urine trouble). Get it? Hahaha. I'm sorry I had to.

[@jeranichols2002]

😏

[@dylanlight4782]

......

[@ffhighwind]

+BBBuilds12 Would've actually been funny if you skipped the explanation and just said "urine" instead of you're in. Also, laughing at your own joke....

[@apenasmeucanal5984]

One part of me says facepalm, the other says lmao, i think that's a win for you

[@kariiiinaxoxo]

😑

[@dskim24]

1. Thank you for the Lebowski reference. 2. Noticed the haircut between part I and part II.

[@emilysaenz6314]

teaching me what my two hr lecture cant

[@Ece579]

You may have actually saved my degree haha. Seriously though, thank you so much! Your videos make revision so much easier and way more fun.

[@RuneyViolet]

"You could have heart failure" with such happy tone made me laugh a lot xD

[@ashleymanney450]

changing the speed to 0.5 = drunk professor :P

[@davidegbufoama804]

I NEVER THOUGHT TO DO THAT THANK U. I didn't like watching Hank's videos when I was in high-school because of how fast I thought he went.

[@Amandamorgan2011]

You just increased my quality of life by 1,000,000 %

[@SheWhoWalksSilently]

IT’S FREAKIN HILARIOUS

[@Alaina-w6y]

Hahaha. Awesome.

[@komalasarikomalasari3523]

this is a good video after listening to it can increase knowledge about the urinary system part 2

[@silvishavira659]

part 2 really helps me to study biomedical, the explanation is very detailed it's just that the language is limited but it's easy to understand

[@neoael]

Loved the 'The Big Lebowski' reference :p

[@desromic]

5:31 Really, CrashCourse? It had to sway in the breeze?

[@zerocalvin]

"Join me, as we journey to the world of pee":- Hank, 2015

[@2Catstitch]

BEST VIDEOS FOR LEARNING... LEARNING IS FUN THIS WAY!!

[@shallbetterdj]

Technically Hank Doctors don't study pee Medical Scientists like me do. Doctors go over it in school but usually in a hospital the nurse or doctor will collect the pee and send it down to the lab for analysis. Most of the urine that comes into the lab will have a quick chemical test, if anything comes up on that test it is examined microscopically and if the Medical Scientists are at a complete lack of words for what is going on (be it either an unidentified crystal or unrecognizable WBC then it will be forwarded to the local Pathologist who will analyze it and tell the doctor what's going on. Your presentation was otherwise flawless with accurate science and proper terms. Good job, and looking forward to next weeks presentation. -DJS Medical Laboratory Scientist (ASCP)

[@the.mermaid.scientist]

MLT here (but going back to school for MLS soon) and we've seen some naaaaaasty urines eh?

[@lalaithan]

Thank you for sharing kind person.

[@sergiomadrigalmora9454]

hank probably knows that

[@benrosenthal5275]

@@sergiomadrigalmora9454 Hank knows all. Hank is God. Hank for President

[@Emily-bk8un]

Your videos have helped me so much this semester but I fell in love when you referenced Lebowski ❤️

[@richardaversa7128]

CrashCourse's animations blow me away every time. And the Big Lebowski references are awesome!

[@hppyshlma]

after I watched a video discussing the urinary system I understood the process of glomerular filtration, where blood is filtered in small thread balls filled with clomerized blood. the higher pressure in the blood must push more plasma out of the capillaries into the glomerulaldehyde. The problem is that the kidneys can only handle so much filtrate at one time, so they must maintain a constant rate of fluid within them. This is known as the glomerular filtration rate, or how much blood passes through the glomerular eye every minute. Antidiuretic hormone or ADH, which is secreted by the pituitary gland post to help the body retain water and stay hydrated. The part of the nephron that reabsorbs water, as water descends, has to move easily through the cells from the filtrate into the blood. specialized protein channels in the membrane called aquaporates that are on the apical or filtrate facing side and the basal or capillary facing side of cells. In contrast, collecting duct landing cells only have aquaporants on the basal side, so not usually much reabsorption occurs there. But ADH triggers those cells to move their stored aquaporan to the apical side, which allows more water to be excreted from the urine. As discussed below, urine enters the thin but muscular urethra by passing through the internal urethral sphincter. the automatic nervous system keeps it awake whenever the body does not urinate. Impulses triggered by stretch receptors go to the pool and other higher brain centers that provide the body with a conscious palate that the body must urinate. Most of these activate the pontine storage area which prevents urination by inhibiting parasympathetic activity and increasing sympathetic output. Of course, the longer you hold it, the more the bladder fills, and eventually the urge to urinate becomes too strong to ignore, at which point the Pontine Mixturation Center goes into action overriding the previous command and opens up the midsection so the body can finally clink.

[@yeyenwahyunim1741]

I have learned a lot about the urinary system and this video really helps me to want to learn more, thank you..

[@ssaf]

thank you, this video really helped me learn about the urinary system and urinary system organs

[@anisajuniarti5192]

Thank you crash course, for making part 2 on the urinary system materia. This material is very difficult to understand but at least this video helps me even a little.

[@keeny24]

I really don't think any host could have made this less awkward. It was totally just another day at work talking to the camera. Just fantastic.

[@kayleebaylee1234]

lol my teacher has been going over this unit for a month and I understood more in this video than any class I've attended

[@raeesahmadtaj]

You are the best bio and chem teacher in world

[@alvia363]

[@arielkruger9547]

AMAZING SERIES. These videos are so helpful! Thanks to you it's so much easier learning the different systems of the bodies (rather than READING all the info)... You absolutely MADE MY DAY with the joke at 0:05 , quoting "The Dude"!

[@ersaalvamayanda371]

Thank you. This video explains in a way that we really understand and the pictures are clear and easy for us to understand

[@mysticgenie]

I have a test on monday and this saved me!! Thank you HANK!!!

[@nazwariandita7162]

thank you, for the video and lesson on how the urinary system regulates urine production and about the anatomy of storing or excreting water.

[@faizhaaura7621]

from the video that has been explained, explaining the urinary system, the factors that affect urine, are quite understandable

[@yahyamohammed9325]

The animation is BEYOND great

[@dindaamelia9980]

From this video we finally get knowledge about the actual excretion of urine

[@indiraprimafebianti9321]

I was given the task by my lecturer to watch this video, the video is very useful and can add insight

[@chockitkat3776]

Never liked biology better until crash course! I love the animation and your sense of humour! Hope all these videos will help me ace my biology 🤣

[@マウ-x7w]

"It totally ruined the Dude's rug which really tied the room together, man." Like the reference

[@annafarhatulauliya7937]

I really like the way of explaining it so it's quickly understood and very detailed how to explain how urine is formed

[@MICREDFIT]

Homedude has single handedly saved my physiology grade

[@mistylee717]

Also I learned the truth about how the process of urination works. Often we don't realize how something really works until it stops working. I have an autonomic nervous system disorder. So my bladder would just decide that now is the time. Lol. And I could not override it. I went for a time where it decided every 15 minutes for hours on end was the time. I was basically disabled. I always had assumed that going potty was a matter of gravity. We voluntarily opened the hatch and gravity did the rest. Nope. It's a contraction. And it is pushed out. At times I felt like I was fighting a war. And sometimes I won. Sometimes not. Sometimes my ANS would just be off by a few seconds. Like I'm just 10 feet from the toilet, can't you wait just a few more seconds? My bladder says: nah close enough.

[@crowsong8097]

Out of curiosity, while you were fighting this (or perhaps if you still are), did you end up using adult diaper-like undergarments? Or were you left to just cross your fingers and hope you could make it? I'm studying to be a veterinary technician, and I know that one of the things we do for dogs is offer a type of hormone replacement therapy. There are also a couple of different drugs we can offer to clients to help reduce their pets' incontinence. Did they have any kind of medication that they offered you to help out with your autonomic nervous system disorder? Thanks for sharing your experience. :D I'm studying the urinary system and this is pretty interesting to me.

[@mistylee717]

+Aaron Simon it seems the only medications they offered were for frequency and they didn't seem to help much. I used some products, mostly just feminine hygiene type things but I preferred not to because the fight was so difficult that it was too tempting to just always let it go. I would become too dependent. So if at all possible I chose to keep up the fight. Sometimes I was literally out of breath by the time I got to the restroom. It is better mostly because of surgery to remove an abscess that seemed to aggravate it. I think the pain of it set off my ANS to constantly try to empty. Also I'm on some meds for other ANS issues involving smooth muscle pain that has made a big difference. Amitriptyline has made a big difference in that and my gastric pain.

[@gkfj9058]

Hats off for your enviable adaptive capability! As a former OCD patients and a medical student who has finished more than half of the med school journey by now, I hold the belief that every health flaw that a human happens to have in his body is counterbalanced by another one that he might not have realised or that has been masked by the suffer of the flaw. I used to have severe obsessive compulsive disorder (OCD) that has not settles down almost completely until about 1-2 years ago after a relatively long period of suffer and endurance that critically jeopardized my academic future. I was despairing regarding the possibility of its being cured ever in my life, but then it did. I then realised that it has added much to my personality, notably my patience, adaptability skills and maybe even more that is yet to be found out. I remember that I have read some literature that patients with OCD tend to have high-pitched observing abilities and tends to be smarter as well (which I don't approve of it completely XD ). The same goes for you Misty. The way you are dealing with your problem reflects masked compensatory features that you are somewhat privileged to have over other non-affected individuals. It is sort of micro-evolutionary processes that are happening behind the scenes somewhere in our body, notably the brain (the plasticity of our brains). Can I ask if the condition you have has a specific name that you may happen to know it? Thanks a lot for sharing your interesting story :)

thank you so much for making these videos, it helps summarize the big picture renal Function. I can return the favor clarifying some language: urinarion is the process of producing urine, technically we are urinating every moment of every day. Micturation is the procession of excreting urine from the body…

[@jdgundy]

One time at a summer camp, it was 120 degrees (in Kansas) and I was at a rifle shooting class and I left early cause I finished everything. I had drank all my water and the water at the range was warm and slimey, and the range was really far from any other sources of water and I collapsed on the way back to camp and woke up 10 minutes later. I "zombied" back to camp and drank like 3 liters of water and like .8 liters of Gatorade and I was peeing every 4 minutes and if I waited any longer my bladder would become unbearably painful like one of the worst pains I've ever felt
