Question

Quizplus · Accepted Answer

Aldosterone secretion is primarily stimulated by Angiotensin II and elevated plasma potassium levels ([K+]). Angiotensin II is part of the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and fluid balance. Elevated potassium levels directly stimulate the adrenal cortex to secrete aldosterone to help maintain electrolyte balance.
