The function of aldosterone is primarily
a. excretion of potassium through the renal tubules.
b. control of sodium and water.
c. regulation of bicarbonate.
d. reabsorption of sodium and potassium.
B
Aldosterone acts on the distal tubule to facilitate sodium and water resorption, resulting in an expanded circulating blood volume and increased blood pressure. When the arterial blood pressure increases, the juxtaglomerular apparatus reduces the release of renin, and the renin-angiotensin-aldosterone system is less active.
