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: -Renin is released into your bloodstream when your blood pressure drops too low or when there’s not enough sodium in your body. Specifically, renin secretion happens when: Baroreceptors (pressure-sensitive receptors) in your arterial vessels detect low blood pressure. Your kidneys detect low salt (sodium) levels.
Detailed explanation-3: -Macula densa cells produce prostaglandins as long as sodium levels are low. These prostaglandins stimulate the release of renin from juxtaglomerular cells.
