Filtrate in the descending limb of the Henle loop has the highest osmolality.

Question

Quizplus · Accepted Answer

The descending limb of the Henle loop is impermeable to ions but permeable to water. As the filtrate passes through the descending limb, water is reabsorbed into the renal medulla, resulting in a concentration of solutes in the filtrate. This leads to an increase in osmolality in the descending limb, making it the region with the highest osmolality in the Henle loop.
