Question

Quizplus · Accepted Answer

The loop of Henle is responsible for creating a concentration gradient in the kidney. The descending limb of the loop is permeable to water but not solutes, allowing water to move out and concentrate the tubular fluid. The ascending limb is impermeable to water but actively transports solutes out, further concentrating the tubular fluid. This gradient plays a crucial role in the kidney's ability to produce concentrated urine.
