I do have to admit, I love your videos, but this needed to focus more on the counter-current. the balance.

Med school student here who wanted to clarify some past comments. This is a solid, basic video to understand countercurrent MULTIPLICATION w/ your typical cortical nephron. Most of the negative comments coming from people who were probably looking for an explanation about countercurrent EXCHANGE which is a DIFFERENT passive process dealing with the vasa recta and juxtamedullary nephrons

It may sound corny but you also have a very pleasant voice as well as tone. So it makes it even better to listen to your very precise and well presented videos.
thank you

[pierredeuj]

i have eargasm listening to this silky smooth voice

[hwyable]

theres no actual explanation on countercurrent mechanism here at

[kaykaysparents]

i just spent the past couple hours watching all of the excretory/urinary system videos. so clear and detailed. just wanted to say thank you!! they are very helpful and just gave me such a more clear understanding of this system!! :)

TY for saving me from mild panic while I tried to make heads or tails of this thing for my exam.

Saved me at least 5 minutes of internal sobbing

i just want to say thank you, i had such a hard time in my anatomy class understanding the physiology of the nephron loop, you explained it well! thanks again

The juxtaglomerular apparatus ( Macula densa) forms when the " thick portion of the ascending limb of Henle" passes through the vascular pore, not the distal convoluted tubule, because the distal comes actually after the macula densa.

This video gives a nice overview of the nephron tubules, even when it doesnt really expalins the countercurrent multiplication.

I'm so attracted to your hand writing

[stacyduncanson]

Of all Khan's video lectures ...  This guys are the very best!!  To the guy who facilitated this video, Thanks for being so awesome at teaching. 

[soledaom]

Genius, you managed to explain me what the profs at university couldn't. Big compliment for your work, I really appreciate it!

[nerveblock]

really need to include the vasa recta, which is where the actual "multiplication" comes from.

My comparativ anatomy exam is tommorrow, and thanks to this video I finally get the freaking nephron! Yay, thank you!

[wendyjones]

One of the most helpful science videos that I've watched! My teacher will be asking about countercurrent multiplication today - now I'll be ready. 

[bigdaddylee]

only the best works at khan's academy. i have so much respect for mr khan for hiring only the very best.

[Arham]

I must respect Khan Academy ....They explain detailed topics In such a simple manner and I thought tht these Topics were too Hard to grasp it😢..I would donate to khan academy

[anomalyp]

If only I had seen this earlier.... It's really well explained!!

[aniketmukhopadhyay]

I was having a hard time trying to understand the counter-current mechanism, but this video made it crystal clear. Thanks a lot!

[yarenot]

Thanks so much for helping me study for my bio IB exam!
