An increase in plasma K+ and activation of the renin-angiotensin pathway both lead to an increase in aldosterone secretion. When plasma K+ levels are high, aldosterone secretion increases to promote the elimination of excess potassium ions from the body. Activation of the renin-angiotensin pathway stimulates the release of aldosterone from the adrenal glands to help regulate blood pressure and electrolyte balance.
