Question

Quizplus · Accepted Answer

The greatest percentage of Na⁺ reabsorption occurs in the proximal tubule, which is the first segment of the renal tubule after the glomerular capsule. Around 65% of Na⁺ and water reabsorption occurs in the proximal tubule, which is responsible for the reabsorption of the majority of filtered solutes. The loop of Henle reabsorbs about 25% of Na⁺, while the distal and collecting tubules are responsible for the remaining 10% of Na⁺ reabsorption.
