What is renin-angiotensin system ? Explain .
Answers
Answer:
The Renin-Angiotensin-Aldosterone System (RAAS) is a hormone system within the body that is essential for the regulation of blood pressure and fluid balance. The system is mainly comprised of the three hormones renin, angiotensin II and aldosterone. Primarily it is regulated by the rate of renal blood flow.
Adrenal cortex: Stimulates release of aldosterone
Hypothalamus: Increases thirst sensation and
stimulates anti-diuretic hormone (ADH) .

Answer:
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. This increases the volume of extracellular fluid in the body, which also increases blood pressure.
The RAAS plays an important role in regulating blood volume and systemic vascular resistance, which together influence cardiac output and arterial pressure.
