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

Question

Quizplus · Accepted Answer

The proximal convoluted tubule is responsible for reabsorbing about two-thirds of filtered Na+ and Cl-. This region of the nephron is highly efficient in reabsorbing valuable solutes and nutrients back into the bloodstream while leaving waste products and excess ions for excretion. Other regions of the nephron, such as the ascending loop of Henle and the distal convoluted tubule, are also involved in Na+ and Cl- reabsorption but to a lesser extent. The glomerulus is responsible for filtration, not reabsorption, while the collecting duct is responsible for final adjustments to urine volume and concentration.
