Question

Quizplus · Accepted Answer

Na⁺ refers to the reabsorption of sodium ions and water in the nephron. This process is always occurring in the descending limb of the nephron loop, but in the ascending limb, it is only reabsorbed under hormonal influence. Specifically, hormones like aldosterone can stimulate the reabsorption of sodium ions in the distal convoluted tubule, leading to increased water reabsorption as well. Therefore, the best choice is C, where Na⁺ is always reabsorbed in the descending limb of the nephron loop, but only reabsorbed in the ascending limb of the nephron loop under hormonal influence in the distal convoluted tubule.
