WebThe renin-angiotensin-aldosterone system (RAAS) plays an important role in regulating blood volume and systemic vascular resistance, which together influence cardiac output and arterial pressure. As the name implies, there are three important components to this system: 1) renin, 2) angiotensin, and 3) aldosterone. WebOverall, the RAAS serves to significantly sharpen the responsiveness of the pressure natriuresis mechanisms to changes in arterial pressure, and thus allows much better physiological fine-tuning of urinary sodium and water excretion to changes in arterial pressure.
