The juxtaglomerular apparatus plays a key role in regulating blood pressure and the rate of blood filtration by the kidneys. It consists of specialized cells in the walls of the renal arterioles that monitor blood pressure and sodium levels. These cells secrete renin in response to low blood pressure or low sodium levels, which in turn leads to the production of angiotensin II, a potent vasoconstrictor that increases blood pressure and stimulates the release of aldosterone to help retain sodium and water. This complex system helps to maintain the appropriate balance of fluids and electrolytes in the body.
