RAAS (Renin- Angiotensin- Aldosterone System)
The Renin-Angiotensin-Aldosterone System (RAAS) is a hormone system that regulates blood pressure and fluid balance. When blood pressure drops, the kidneys release renin, which triggers a chain reaction: renin converts angiotensinogen into angiotensin I, then ACE converts it into angiotensin II. Angiotensin II causes blood vessels to constrict, increases blood pressure, and stimulates the release of aldosterone, which makes the kidneys retain sodium and water, further raising blood pressure.
