Where are solute and water reabsorption independently regulated?
|
Loop of Henle
|
|
Proximal convoluted tubule
|
|
Distal convoluted tubule
|
|
Descending LOH only
|
Explanation:
Detailed explanation-1: -Reabsorption in the thick ascending limb: A further 25% of the sodium and potassium is reabsorbed through the walls of the thick ascending limb of the loop of Henle via: Three-ion cotransporter (sodium/potassium/chloride) and the sodium/potassium ATPase, which as before maintains the sodium concentration gradient.
Detailed explanation-2: -The descending limb of the loop of Henle is relatively impermeable to solutes and freely permeable to water.
