Where does the greatest percentage of Na⁺ reabsorption takes place?

Question

Quizplus · Accepted Answer

The majority (about 65-70%) of Na⁺ reabsorption occurs in the proximal tubule, which is the first segment of the renal tubule after the glomerulus. The loop of Henle (option B) reabsorbs mainly water and electrolytes, but not Na⁺. The distal tubule (option C) and collecting tubule (option D) are responsible for fine-tuning the reabsorption of Na⁺, but they do not reabsorb the majority of it.
