What is the Origin of Renin-Angiotensin-Aldosterone System?

The individual components of the RAAS were discovered sequentially throughout the 20th century, with the full, interconnected system being elucidated by the 1970s. Renin was identified in the late 19th century, followed by angiotensin and aldosterone. Understanding this system has been foundational to the development of several major classes of cardiovascular medications.

What is the Mechanism of Renin-Angiotensin-Aldosterone System?

The cascade begins with the kidney releasing the enzyme renin in response to low blood pressure. Renin cleaves angiotensinogen to form angiotensin I, which is then converted to the potent vasoconstrictor angiotensin II by Angiotensin-Converting Enzyme, primarily in the lungs. Angiotensin II acts on AT1 receptors to cause vasoconstriction and stimulates the adrenal cortex to release aldosterone, which promotes sodium and water reabsorption in the kidneys, thereby increasing blood volume and pressure.

Renin-Angiotensin-Aldosterone System

Meaning

The Renin-Angiotensin-Aldosterone System is a complex, multi-organ hormonal cascade that plays a pivotal role in regulating blood pressure, fluid and electrolyte balance, and systemic vascular resistance. This neuroendocrine pathway is a crucial homeostatic mechanism that responds primarily to decreased renal perfusion or sympathetic nervous system activation. Dysregulation of the RAAS is central to the pathophysiology of hypertension and heart failure.
