The way by which renin controls hypotension
WebJul 30, 2024 · Renin is an enzyme that is produced by the granular cells of the afferent arteriole at the JGA. It enzymatically converts angiotensinogen (made by the liver, freely circulating) into angiotensin I. Its release is stimulated by prostaglandins and NO from the JGA in response to decreased extracellular fluid volume. WebJun 13, 2024 · The body has 2 main compensatory mechanisms in place to regulate blood pressure when hypotension is present: the sympathetic nervous system and the renin angiotensin aldosterone system. These 2 systems work synergistically to improve blood pressure and perfusion, and we will be walking through the steps the body takes to make …
