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.

why am I eating breakfast while watching this?
"Its other main duty"😂
Foking normies up on this comment section
I hope my teacher died no cap
online classes have been so hard. thank you for this
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
damn this is complicated haha
I like how this dude literally explained how the urinary system works faster then any of my 6th and 7th grade teachers
Quality video geared towards actual learning! Thank you much!
the only thing is less in him is that is not God of anatomy
my a & p final is tomorrow:((
did not understand a lick of this
Its amazing how even though he is reading it sounds like he knows what he is reading.
Thank you for this wonderful vedio sir
How can people believe that everything, including the complex kidney's, was created from nothing over billions of years? That's like leaving your garage empty for a million years and expecting a Mercedes Benz to magically build itself from nothing over millions of years. And everything on earth, including our bodies and its complex systems, are even more complex and intelligently designed than a Mercedes Benz. So it's even more absurd to believe the scientific impossibility that nothing created everything.
why do i have such a short attention span
this is soo boring im tired … who remember this stuff when working anyway…. is being a nurse even worth it.
such beautiful animations. God bless ya'll fr
Can you please slow down a little. My head is gonna explode 🤯
one part i am hung up on, is he saying water and urea from the filtrate release through the collecting duct, into the medulla tissue?
This is amazing! For Funeral Services ( embalming) , this is great before doing my exam tomorrow. Thank You!!
I knew nothing about kidneys before watching this. Let’s see what I understood. Kidneys bring blood in to remove cellular waste produced by the rest of the body. Then they put good stuff back into the blood. Like a double filtration. It’s like a coffee filter, but two ways. They are centrally located within the body, so that helps to conserve energy used to pump the massive amount of blood to them that they need to filter (at any given time, 20% of your blood is in your kidneys, making pee). After the double filtration, the waste is sent to the bladder. When the bladder fills, you have to pee it out. It seems like it would be more efficient to pump the water back into the body, but I guess this is not possible since the urea must be dissolved in something in order to be expelled? But if there is excess water, why doesn’t some of it get pumped back into the body? I guess evolution isn’t perfect? Or is there a reason for this?
Beyond that? Yea that technical jargon went way over my head. Not important to me since I don’t have to pass some stupid test

why don't you make videoes anymore???????!!!!!!!!
our bodies are masterminds
why do u have to talk at this speed? the video is great . the speed is too fast for absorption
love it
So how does the blood flow from the arteries, nephron, and veins? I'm a little confused as to which is first?
Anyone from 9c watching this?
WOW
WOW
im in 6th grade and i have to learn this learn this lol
Great, now i gotta pee.
awryyyyyy
We worship u before tests
thanks for the nice vid
From the middle east شكرا
Crash course is so underrated, wish more schools would incorporate videos like this
This guy speaks at playback speed of 2x lol
wow thx man this helps
I still can’t find a single video that explains how the water you drink gets to your kidneys
Why nehrone called reabsorbing and regular basis process?
take your time and talk slow man
