Question

Quizplus · Accepted Answer

Aldosterone is a hormone secreted by the adrenal cortex that stimulates the distal tubule of the nephron to reabsorb sodium ions (Na+), thus increasing blood volume and blood pressure. It does not affect the proximal tubule or the collecting duct membrane permeability to water.
