The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the ________.
A) collecting duct
B) glomerular filtration membrane
C) nephron loop
D) distal convoluted tubule

Question

Quizplus · Accepted Answer

The nephron loop plays a critical role in establishing the medullary osmotic gradient due to its unique permeability properties. The descending limb is highly permeable to water while the ascending limb is selectively permeable to ions, creating a concentration gradient that drives the reabsorption of salt and water.
