Counter current mechanism in kidney - Concept and exam oriented

Hi I am Dr.Raghu, Welcome to my channel
• Dr. Raghu's Playlist -...
• Short term regulation ...
In this video, I discuss the counter current mechanism which operates in kidney in order to concentrate the urine. The video is divided into
1. Brief introduction
2. Counter current multiplier - Loop of Henle
3. Role of urea
4. Counter current exchanger - Vasa recta
5. Summary

Sir I don't know what you tube algorithm is upto ... whenever I opened my yt to see something on physiology only some channels pop up that I already know but why your channel doesn't come in feed 😔 ...I 'm grateful after a long time somehow I found this channel .. ...I wish u happiness and success

[@Dr.Raghu-simplified_classes]

Thanks a lot for such a lovely comment. I think at least now YT algorithm will look into it😊.
M glad u found my channel. I wish u successs in your exams.
Do share my videos among your friends as well juniors.

Sir do the ions enter the descending loop of henle from the interstitium to maintain the osmalarity???
It is given like this in the textbook

7:22
Sir,
Less osmolar fluid contains higher amount of water and Vice versa( conc. of ions is remaining same in that part) .
So in 7:22 , I think water should move from 200 to 400 mosmol/L ...
And sir, according to you, if 200 mosmol/L is getting more water...then its osmolarity should decrease further...as osmolarity is inversely proportional to vol of water.
Please 🙏 clear this doubt sir...
Btw sir, your explanation and content are top notch 👌 🤩🙏..

[@Dr.Raghu-simplified_classes]

But the ascending limb is impermeable to water. When osmolarity is decreased in descending limb, as u said, water moves from descending limb into interstitium, because descending limb is permeable to water and not to ions.

Sir we need acid base balance topic in renal physiology..,🥺🥺🙏

[@srimaasangita9485]

Sir, at 6:40 , u hv mentioned water moves out to interstitium from descending limb till the equilibrium reached. If water is going out, why interstitium osmolarity is not decreasing as its water is increasing here.
Can u explain, please.
And sir, ur videos are awesome.

[@Dr.Raghu-simplified_classes]

Water is going to move till equilibrium is reached. And equilibrium is reached till the concentration in descending limb is 400. That's what osmosis is...isn't it ?

[@v.krishnabalan3660]

I have same doubt sir since water is moving to interstitium from des limb by osmosis why interstitium osmolarity is not decreasing since its receiving water

[@DeepakS223s]

Remember at the same time ions move out from ascending loh into interstitium which counteracts the water from descending loh moving into interstitium so osmolarity doesnt decrease

[@gollapalliraji9580]

Thank you sir

[@Dr.Raghu-simplified_classes]

TQ

[@harshakumarragunta558]

@6:20 when the water from descending limb of LOH Is coming out into medullary interstitium how can its concentration be still 400mosml/lt,,,it decreases ryt as water comes in ,ig the equilibrium attained would 350 -350 in descending and interstitium 😐
