The juxtaglomerular complex, also known as the juxtaglomerular apparatus, is a specialized structure located in the kidney, specifically where the distal convoluted tubule contacts the afferent arterioles of the glomerulus. It is composed of three main components: juxtaglomerular cells, macula densa cells, and extraglomerular mesangial cells. This complex plays a crucial role in regulating blood pressure and glomerular filtration rate by sensing sodium chloride levels and releasing renin, which is involved in the renin-angiotensin-aldosterone system.
The juxtamedullary complex is also called the juxtaglomerular capsule, and it functions in the kidneys to do filtration. Another name for it is the Bowman's capsule.

Renin is the enzyme secreted by the juxtaglomerular apparatus.
One way the kidney increases systemic blood pressure is to increase secretion of renin by the juxtaglomerular complex.

The juxtaglomerular apparatus is a specialized structure found in the kidney that regulates blood pressure and kidney function. It consists of the macula densa, juxtaglomerular cells, and extraglomerular mesangial cells, which work together to control the release of renin and the constriction of blood vessels.

Juxtaglomerular cells are derived from smooth muscle cells of the afferent arterioles in the kidney. They play a key role in regulating blood pressure and kidney function by secreting renin.
Renin is the enzyme released by juxtaglomerular cells. It plays a key role in the renin-angiotensin-aldosterone system, which helps regulate blood pressure and fluid balance in the body.
