Question

Quizplus · Accepted Answer

The juxtaglomerular complex (JGC) is an important structure for blood pressure regulation. It is located at the point where the distal convoluted tubule of the nephron comes into contact with the afferent arteriole that supplies blood to the glomerulus. The JGC contains specialized cells called juxtaglomerular cells which release the hormone renin in response to changes in blood pressure. Renin then triggers a series of events that ultimately lead to an increase in blood pressure, helping to maintain proper blood flow and organ function.
