WebMar 12, 2024 · The renin-angiotensin-aldosterone system (RAAS) is a critical regulator of blood volume, electrolyte balance, and systemic vascular resistance. While the baroreceptor reflex responds short term to decreased arterial pressure, the RAAS is responsible for acute and chronic alterations. The classical understanding of RAAS is that it comprises ... WebThe renin angiotensin system (RAS) is a key homeostatic regulator that relies on feedback regulation to achieve and sustain the delicate balance required for healthy physiological function. A number of negative feedback loops exist within the RAS that counterbalance the effects of conventional RAS blockade. Indeed, instead of reducing levels of ...
