The Renin-Angiotensin System (RAS), also known as the Renin-Angiotensin-Aldosterone System (RAAS), is a critically important hormonal cascade that regulates blood pressure, fluid balance, and electrolyte homeostasis. This diagram visually outlines the key components and sequential activation of the RAS, from the initial release of renin by the kidneys to the final actions of angiotensin II and aldosterone on the body. Understanding this system is fundamental to grasping the pathophysiology of hypertension and various kidney disorders.
