What Is the Raa Pathway

The RAAS is a complex multi-organ endocrine (hormone) system involved in the regulation of blood pressure by balancing fluid and electrolyte levels, as well as regulating vascular resistance & tone. RAAS regulates sodium and water absorption in the kidney thus directly having an impact on systemic blood pressure.

What is the RAAS system in biology?

The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure and fluid and electrolyte balance, as well as systemic vascular resistance.

How do you remember RAAS?

  1. RENin = RENal (Renin is released by the kidneys)
  2. AngiotensinoGIN = GIN/alcohol = Liver (Angiotensinogen is released by the liver)
  3. ACE = AIR = Lungs (ACE is found within the lungs)
