The reninâangiotensin system (RAS) or the reninâangiotensinâaldosterone system (RAAS) is a hormone system that regulates blood pressure and fluid balance.ngiotensin II also stimulates the secretion of the hormone aldosterone from the adrenal cortex. Aldosterone causes the tubules of the kidneys to increase the reabsorption of sodium and water into the blood, while at the same time causing the excretion of potassium (to maintain electrochemical balance).
Aldosterone is a steroid hormone which is secreted from the zona glomerulosa of the adrenal gland. It has a mineralocorticoid activity and is the most important regulator of plasma potassium. When plasma potassium increases, increased stimulation of aldosterone occurs directly and also as a result of the Renin-Angiotensin-Aldosterone System (RAAS).
