What region of the nephron reabsorbs about two-thirds of filtered Na⁺ and Cl^-?

Question

Quizplus · Accepted Answer

The proximal convoluted tubule reabsorbs about two-thirds of filtered Na+ and Cl-. This is the first region of the nephron where reabsorption occurs, and it is highly permeable to water and solutes. The ascending loop of Henle reabsorbs Na+ and Cl-, but only about 20-25% of filtered amounts. The glomerulus filters blood and is not involved in reabsorption. The distal convoluted tubule and collecting duct play roles in regulating electrolyte and water balance, but do not reabsorb as much Na+ and Cl- as the proximal convoluted tubule.
