❗Note: There's a clarification at 8:05. During urea recirculation, the THICK ascending limb, the DCT and the cortical collecting duct are all relatively less permeable to urea. The THIN limbs of the loop are more permeable (ascending > descending). Urea enters through the thin limbs and then goes through the rest of the nephron, recirculating through the terminal parts of the nephron. I hope this helps! :)

I feel energized after seeing this type of clear concepts😍😍
one very important concept should be mentioned is that the blood flows the opposite direction of fluid in loop of Henle. if they move in the same direction, more water would be accumulated in medullary interstitium around descending LOH and dilute the gradient. and also one correction, water is stilll reabsorbed in medullary collecting duct until it reaches equilibrium with medullary interstitium. thats why the opposite blood flow is important as it takes water away

But in medical references they say the opposite, which is nonsense

I was stuck on this part, wondering why the medullary interstitium doesnt reach equilibrium due to the water flowing in, and it finally makes sense THANK YOU
have my physiology final in a few days and your rapid review of this is absolutely saving my life, thank you!

This is the best video on counter current mechanism I have ever seen. And the voice is just woww
Your eloquence makes this easy to understand. Thanks ❤️
I think this area of the kidney is some of the most challenging physiology to understand and you did splendid.
First time ever in my life, i understood this concept. Thank you
you're single-handedly saving me in medical school
BEST VIDEO IVE FOUND ON COUNTERCURRENT MECHANISM!! love the way u dumb these concepts down with ur clear and concise delivery
Excellent! Very helpful. Super clear voice, the pace is just right to follow such a tough topic, and the cartoon illustrations are great too. THANK YOU SO MUCH!
Please keep making such videos Thanks a ton I would hav never understood better❤️
you're an absolute lifesaver!
Thank you ! Thou art the divine saviour in animal physiology !
Thank you so much for this. You made it super easy to understand! 😭❤️❤️
Best explanation I've seen so far as a visual learner.
You deserve a million likes for simplifying this imp topic💙
finally ending of so much sufferings, too easy to understand...thank You very much Mam! God bless!

This is a great video. 10 mins and I've learned it, well summarised.
thank you for this, it was very helpful!
Thanks 😊😊 for made me more clarification on renal physiology
Your video cleared my doubts regarding this topic and also this visual will help me retain this info for longer time. Thankyou for this amazing video.
wow!! turns out that one the weakest topic of mine has improved a lot through this video, Thankyou
These videos are really helpful, thank you so much!
