Which statement is false regarding the function of aldosterone in regulating urine volume and concentration?
A) When aldosterone levels are up, urine output is increased with both water and sodium conserved in the blood, and decreased potassium in urine.
B) When aldosterone levels are up, more sodium ions are actively transported from the tubule to the peritubular capillaries.
C) When aldosterone levels are up, more potassium ions are secreted.
D) When aldosterone levels are up, urine output is reduced with both water and sodium conserved in the blood, and increased potassium in urine.

Question

Quizplus · Accepted Answer

Aldosterone is a mineralocorticoid produced in the adrenal cortex that targets the kidney. It regulates the amount of active transport in the nephron. If aldosterone levels are up, more sodium ions are actively transported from the tubule to the peritubular capillaries, and more potassium ions are secreted. Water follows the sodium by osmosis, so more water moves to the peritubular capillaries, too. The result of aldosterone secretion is reduced urine output with both water and sodium conserved in the blood, and increased potassium in urine.
