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.
juxtaglomerular apparatus
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.

Juxtaglomerular apparatus
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.

The cells of the juxtaglomerular complex of the nephron. Granular cells in the kidney monitor alteration in blood pressure. If blood pressure falls and remains low, this specialized cells release the enzyme renin into the blood stream.
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.
