  The   Renin–Angiotensin–Aldosterone System  (RAAS)   is one of the most important hormonal systems in the human body responsible for regulating   blood pressure, blood volume, and electrolyte balance . It is a key concept in   human physiology   and frequently appears in topics related to cardiovascular and renal regulation for students preparing for   NEET-UG   and studying   CBSE  Biology . What is the RAAS System? The  Renin–Angiotensin–Aldosterone System (RAAS)  is a complex hormonal cascade that is activated when the body experiences: Low blood pressure Low sodium levels Reduced blood volume Reduced blood flow to the kidneys Its main purpose is to  restore normal blood pressure and maintain fluid balance in the body . Key Organs Involved in RAAS Several organs work together to regulate this system: Kidneys  – release the enzyme  renin Liver  – produces  angiotensinogen Lungs  – contain ...
