In the slide that appears from 2:38, the text below states: Due to the ion movement out of the DESCENDING limb of Loop of Henle. It should say ASCENDING, because the descending limb in impermeable to solutes.

A bit confused the osmolarity is getting higher as the loop of Henle descends downward. I am assuming bc it is only permeable to water it is following its concentration gradient but it unable to provide enough to have enough solvent/solution. Which makes me think the driving force is coming from the ascending limb?

@@aamirkhan18111 Wow, that is super interesting... so, since the renal medulla essentially has the same osmolarity throughout the interstitium how does the vasa recta do its thing? Assuming on the arterial capillary end solutes enter towards the top of the capillary loop at until the twist which we see in images ... at which point the gradient switches and they start to leave keeping the osmolarity the same towards the end and entering into the venule? All super interesting... thank you for taking your time to expand on this topic. Really appreciated!

@@aamirkhan18111hello can i ask why when water goes to the medullary interstitium there is no a decrease in osmolarity in the medullary interstitium? I mean the osmolarity in the iterstitium stay the same (example, in the intersititum is 400 and in the descending tubule is 300. And then water goes to the interstitium and makes it 400 = 400, why the osmolarity of the interstitium stay the same? Shouldnt it be decreases?) Im sorry for my bad english :)
