WebRenin secretion is regulated by the combined operation of directly acting peripheral stimuli. One of the principal regulators is an intra-renal baroreceptor mechanism; decreases in renal arteriolar pressure increase renin secretion, possibly by a direct effect of pressure on the juxtaglomerular cells ( Davis and Freeman, 1976 ). WebMay 13, 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 …
