Renin is an enzyme produced by the kidneys that plays a crucial role in the regulation of blood pressure and fluid balance. It initiates the renin-angiotensin-aldosterone system (RAAS) by converting angiotensinogen, a protein produced by the liver, into angiotensin I. This process ultimately leads to the production of angiotensin II, a potent vasoconstrictor that increases blood pressure and stimulates aldosterone release, promoting sodium and water retention. Renin's activity is primarily regulated by blood pressure, sodium concentration, and sympathetic nervous system activity.
