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 helps to control the amount of fluid in the body by affecting how much salt and water the kidney retains or excretes.The adrenal glands produce aldosterone in response to another hormone called renin.Renin is produced by specialised cells in the kidney that detect when the body is dehydrated; renin released by the kidney signals the adrenal glands to release aldosterone.ldosterone helps to control the amount of fluid in the body by affecting how much salt and water the kidney retains or excretes.
