WebOne piece is angiotensin I. Angiotensin I, which is inactive (doesn’t cause any effects), is split into pieces by angiotensin-converting enzyme (ACE), which your lungs make. One of those pieces is angiotensin II, an active hormone. Angiotensin II causes the muscular walls of small arteries (arterioles) to constrict, increasing blood pressure. WebJul 30, 2024 · Renin–Angiotensin–Aldosterone. 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.
