The renin-angiotensin-aldosterone system regulates blood pressure and water balance by converting angiotensinogen into angiotensin I and then angiotensin II.
The renin-angiotensin-aldosterone system (RAAS) is a hormone system that regulates blood pressure and water balance in the body. Renin, produced by the kidneys, acts on angiotensinogen to form angiotensin I, which is then converted to angiotensin II by angiotensin-converting enzyme (ACE). Angiotensin II plays a crucial role in raising blood pressure through vasoconstriction and stimulating the release of aldosterone from the adrenal cortex.
