Detailed explanation-1: -The main source of renin is the juxtaglomerular cells (JGCs), which release renin from storage granules. Besides the renin-angiotensin system (RAS) in the JGCs, there exist local RASs in various tissues.
Detailed explanation-2: -Juxtaglomerular cells are sensors that manufacture and release the hormone-enzyme renin in response to minute changes in BP and the composition and volume of the extracellular fluid.
Detailed explanation-3: -Juxtaglomerular cells are responsible for the production, storage, and release of a hormone called renin which regulates blood pressure. They are also called granular cells as they have a large amount of renin-secreting granules. They sense the blood pressure in the arteriole and release an adequate amount of renin.
