Tyrone Hurst an IT in Ireland. I had a choice between two long questions. One was on all of these topics, the other was on molluscs. I'm still salty over it because it didn't really give me a choice.

You know, whenever I go to other channels for information about medicine ( I'm a medical student) I got confused! Even good and informative channels out there are not able to explain things the way you do! Your amazing! Simple but at the same time complex and detailed and informative! And also I have to say that I didn't understand anything by reading the textbook but now that I'm watching your playlist on the topic of unrinary system, I'm understanding everything easily and in detail!! Thank you for beingg here and sharing your content free as many students like me are not able to pay for even low amounts of membership fees. ❤🙏

This is great, makes so much more sense now that you explained it! Thank you!!

how could u ever dislike this video...? I mean, just, nonsensical. thank you kind sir for your greatness for all us struggling biology students. I salute you.

Thanks so much! I’m started off as a lab tech, and then became a general radiology tech, but forgot all of this, but now due to short bowel syndrome causing renal failure (Crohns disease, intestinal cancer, and 37 surgeries left me with only 4.9% of my entire GI tract), I went into full on renal failure and countless renal calculi, I discovered what little intestine left (I on my 8th ileostomy, including a j pouch and two failed k pouches) can’t absorb enough fluid and nutrients to keep my internal organ alive and healthy. I lost all my notes from collage due to a house fire, so thanks so much for the refresher, now I remember everything (graduated from the university of Toronto way back knowing 1992 with my masters in lab medicine and in 1996 with my masters in medical radiological medicine). Finally got hold of the lab work for the past 2 years, with my creatinine at 150 at its lowest, and no one told me, so I went into renal failure 3 weeks ago with my level at 271! If it weren’t for my stones, I’d still be oblivious to it, being totally asymptomatic! (Having 37 GI surgeries, you tent to ignore little problems that should really be lid attention to). Can’t believe I’d forgotten everything you just showed, I’m in your debt my friend, now I have the tools necessary to get back to normal renal function…stated myself in 1 L if saline infusions via a single lumen PICC line every other day….I’m down to 130, almost normal, and fell 100% better, especially now that I can remember all the details thanks to your video! All the best, cheers!

Thankyou for this very useful video! You did make others love biology more! :)

"Earn the name urine" lol

Thank you for a very descriptive video! not many " teachers" take their time explaining such detailed systems.

I find the conversational tone much easier to understand than the very rehersed professional sounding narrations from other videos.

THANK YOU SOOOOOOOOOOOOO MUCH!!!!! I didn't understand anything in kidneys, but this helped SO much!!! Thank you so so much :D I have my ig tmrw and thanks to you I may just pass

Why in the world can't my teacher say it simply like this.

I have been doing well in my class but all I have been doing is memorizing the textbook and regurgitating it back when I take the exams. But by watching your videos, I actually UNDERSTAND the material. It's really sad that college students all around the world are paying hundreds of thousands of dollars and not learning anything.

Thank you for the great video! To avoid confusion, the descending limb is not ONLY permeable to water it is also partially permeable to ions but for the sake of explaining, he simplified the concept to make it easier to understand.

awesome explanation!!!

The fact that you take the time to do these illustrations is greatly appreciated. My A&P professor is awesome, but to get a different perspective helps alot, love the garbage chute analogy. I thought of it as the show Hoarders, where the family throws out junk (ascending part of loop of henle) and the hoarder picks thru reabsorbs the junk at the in the descending end as the garbage men are getting ready to load it. The collecting duct is the garbage truck. Thanks again, you rock !!!

hey guys if you're looking for help in anatomy check out "Wendy Riggs" channel. she really makes anatomy and histology simple and fun.

truly one of the best videos I have ever watched on youtube about urinary system.. thanks a lot

Didnt understand it for 2 weeks in class . Now i get it in 18minutes. Lifr is amazing

''later excrete when we find a suitable time" lololol

Thanks this make more sense to me. I am just paying my teachers tons of dollars for not properly teaching me. Shame on them.

Thank you!! I have a Renal Physiology test on Monday and I was totally lost before watching this video.

brilliant design! fascinating how complex and perfect the human body's systems have to be for the entire organism to survive.

Oh my gosh! Thank You! This was SO helpful! I wish I had found you at the beginning of the semester! I currently have a professor that doesn't teach but "reads" to us from the book! Thank You!

I logged in just to thank you for the great explanation. I will now think about you every time my bladder empties

This guy is an effing genius. If there is a paypal account I swear I'll donate because I have learnt a heck of alot more from this one youtube video than I did in 2 weeks worth of lectures on the Urinary System. THANK YOU SO MUCH. I may just get a distinction on my exam now.

Not only was that helpful for an upcoming exam, but it was absolutely easy to understand and truly cool. You sure know how to explain stuff!

Wow, you've managed to clearly explain in 18 minutes what a 3 hours A&P Lecture failed. Good on ya and thanks.

Your videos are so incredibly helpful!

Khan academy rocks! Using this as a revision tool for my part 1 Emergency Medicine Specialist exam. A great, clear and concise overview. Thank you for making suck great quality education free to success for everyone :))))

GOD is great who created man and the entire universe. As a student , thanks for this video which helps me a lot.

I spend more time on KZread getting better understandings of various topics and retain more information because of vids like these. Super helpful, thanks for doing the job college instructors are getting paid to do, yet don't don't do as thoroughly.

whenever i watch these types of explanation videos, i find it helpful to just watch it first. let your brain absorb the info, then on the second watch, pull out your pen and paper!

I've been reading the textbook again and again hoping to understand this process but this 18 min video made me thoroughly get it. You, Sir, is a legend

this is my 1st time being able to really understand anatomy. thanks to you!

This video is the only one I have watched that made sense.

Sal khan was sent to us from heaven 🙏

Also.....the one thing we all love from Sal...."Lemme switch colors"

Thank you. I understand so much better. Wish my teacher was as good as you.

This vid was published in 2010 and is helping me out in 2020. Tnx alot

I am doing A-level biology on my own. LIFE SAVER. LITERALLY. I wouldn't have understood anything if it weren't for these videos! Many thanks

OMG thank you so much! you helped me finish college last year and this year you guys are hopefully helping me to pass my year 1 pharmacy exams. thank you for all the work you do.

I don't know how to thank you! that was just perfect! totally perfect! thank you from all my heart, wish we had teachers like you.

Khan, it's like you're a walking encyclopedia..or textbook. How could one person possibly know so much? I admire you man. Keep it up

You actually drawing it out makes it much easier to understand. I thank you sincerely.

Thank you from a studet from Yerevan State Medical University!!!!!!!!!!!!!!!!!!!!!!You helped me a lot to understand this topic and to preper for my control work,which will start from 2 days!!!!!!!!!

You are honestly a hero. In every sense of the word. I go to arguably the most prestigious institution in the world and you make things so much simpler.

I will never waste time in lecture again!! This was very helpful! Thanks!

Very interesting. Was just diagnosed with Stage III kidney failure. Its great to see how the organ works

SO helpful! Gonna ace my anatomy test tommorrow now! Thanks!!! :-)

thank you!! this pretty much saved me for my test tomorrow! didn't quite understand which parts of the nephron did what until now :)

this is the best vidio i have ever seen on youtube that helps you with everything there is to know about the kidneys and the nephron for the exames work b test a test and even just for general information if there is anything you want to know about this is definitely the best place ever to learn and study from.By just listening to this vidio 3 times i was able to achieve a ten in all my exams and now i am able to answer any questions that anyone asks me since i have learned this vidio ofby heart

Your anatomy videos are great! Thanks Sal!

you're my saviour Mr. Khan! If you made a video of every topic I study in bio class. You explain everything in a quarter of the time it takes for my lecturer to AND you make it so easy to understand! I really can't thank you enough and I'm sure a lot of people feel the same way.

This videos are so useful for medical students!thank you
