Question about Loop of Henle

05231991

Is the fluid coming out at the end of the ascending limb more concentrated and lesser in volume?

Thank you.

Does ADH effects the permeability of the Loop of Henle or the collecting duct? I seem to have contradicting notes :s:

ADH affects the permeability of the collecting duct definitely, not sure about the loop. On a side note, just to add more confusion, I think I read somewhere that it affects the permeability of the CD, and the distal convoluted tubule.

My notes which say it affects the collecting duct also says that if affects the DCT. So, you are probably right.

Ah, so yeah it probably is the DCT and the CD, but not the loop of H.

I'd just google it tbh

ADH - also known as Vasopressin, just in case you ever come across that - affects the permeability of the collecting ducts to water. Essentially, it causes the collecting ducts to increase expression of water-molecule-permeable proteins known as aquaporin-2, thereby allowing more water to be retained.

Renal physiology ftw :p:
