Renin–angiotensin system - Wikipedia
The renin-angiotensin system (RAS), or renin-angiotensin-aldosterone system (RAAS), is a hormone system that regulates blood pressure, fluid, and electrolyte balance, and systemic vascular resistance.
Renin-Angiotensin-Aldosterone System (RAAS) - Cleveland Clinic
2022年9月13日 · The renin-angiotensin-aldosterone system (RAAS) involves several steps, including: When your blood pressure falls, your kidneys release the enzyme renin into your bloodstream. Renin splits angiotensinogen, a protein your liver makes and releases, into pieces. One piece is the hormone angiotensin I.

2023年3月12日 · 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.
Renin-Angiotensin System: Updated Understanding and Role in ...
The renin-angiotensin system (RAS) is a complex hormonal pathway that is a critical regulator of blood volume, electrolyte balance, and systemic vascular resistance. The classical understanding of RAS is that it comprises three significant components: renin, angiotensin II, and aldosterone [1, 2].

Renin-Angiotensin-Aldosterone System - CV Physiology
The renin-angiotensin-aldosterone pathway is not only regulated by the mechanisms that stimulate renin release, but it is also modulated by natriuretic peptides released by the heart. These natriuretic peptides act as an important counter-regulatory system.
