Renin is an enzyme produced by specialized cells in the kidneys called juxtaglomerular cells. It plays a crucial role in regulating blood pressure and fluid balance by initiating a cascade of reactions that lead to the production of angiotensin II, a potent vasoconstrictor. Renin acts as a key player in the renin-angiotensin-aldosterone system, which helps regulate blood volume, electrolyte balance, and systemic vascular resistance.
