The reabsorption of water in the nephron is accomplished as it follows the osmotic gradient created by Na⁺ reabsorption.

Question

Quizplus · Accepted Answer

Water reabsorption in the nephron occurs through osmosis, which is driven by the concentration gradient of solutes like Na+, Cl-, K+, and P. Reabsorption of these solutes, particularly Na+, creates an osmotic gradient that draws water out of the urine and back into the bloodstream. This process occurs in the proximal tubule and the loop of Henle.
