Question

Quizplus · Accepted Answer

Aldosterone is a hormone secreted by the adrenal gland that stimulates the reabsorption of sodium ions and water by the kidneys, thereby increasing blood volume and blood pressure. It does this by binding to specific receptors in the cells of the distal tubules and collecting ducts of the kidneys, increasing the activity of sodium-potassium pumps on the membrane of the tubule cells, and promoting the reabsorption of sodium ions and the excretion of potassium ions.
