Question

Quizplus · Accepted Answer

An increase in the level of potassium ions in the ECF leads to an increase in the secretion of aldosterone from the adrenal cortex. Aldosterone promotes the reabsorption of sodium ions in the distal tubules and collecting ducts of the kidneys, while promoting the excretion of potassium ions. This helps to restore the balance of potassium in the ECF.
