Question

Quizplus · Accepted Answer

The loop of Henle of the juxtamedullary nephron extends deep into the medulla of the kidney and has a thick ascending limb and a thin descending limb. The ascending limb actively pumps out sodium and chloride ions, creating a high solute concentration in the medulla. The descending limb is permeable to water, allowing it to passively leave the nephron and be reabsorbed by the surrounding capillaries. This process creates a concentration gradient that establishes the vertical osmotic gradient in the medulla of the kidney.
