As the tubular filtrate moves through the descending limb of the loop of Henle,the osmolality of the filtrate increases.

Question

Quizplus · Accepted Answer

The descending limb of the loop of Henle is permeable to water but not to solutes. As water diffuses out of the tubular filtrate into the surrounding tissue (which has a higher osmolality), the concentration of solutes in the filtrate increases, leading to an increase in osmolality.
