Quizplus · Accepted Answer

A rising potassium ion concentration is an important stimulus for the secretion of aldosterone, as aldosterone promotes the reabsorption of sodium ions and the excretion of potassium ions in the kidneys, and thus helps to regulate potassium levels in the body. Falling potassium ion concentration would actually decrease the stimulus for aldosterone secretion, whereas rising sodium or calcium ion concentrations do not directly stimulate aldosterone secretion.
