Question

Quizplus · Accepted Answer

Aldosterone stimulates the reabsorption of sodium ions and water in the kidneys, which helps to increase blood volume and maintain blood pressure. This is achieved through the activation of sodium-potassium pumps in the epithelial cells of the distal convoluted tubule and collecting ducts. This results in increased sodium reabsorption and a subsequent increase in water reabsorption, leading to a decrease in urine output.
