Question

Explain how Renin is involved in maintaing blodd pressure? Explain

Answer 1

Renin is a part of Renin Angiotensin Aldosterone System of our body which is primarily the most important system that regulates Blood Pressure.Any drop in blood pressure translates into a drop in Fluid Volume inside blood vessel that supplies to the Kidneys that results in a decrease GFR(Glomerular Filteration Rate).This is sensed by the Kidneys and Renin is released from the Kidneys.Renin acts on Angiotensinogen produced by Liver and converts it into Angiotensin-1.Angiotensin-1 gets converted into Angiotensin-2 by Angiotensin Converting Enzyme produced by Lungs.This Angiotensin-2 raises the Blood pressure by causing Vasoconstriction(narrowing blood vessels)and by stimulating release of Aldosterone(causes Salt and water retention from Kidney) from Adrenal glands.
