What is the Juxtaglomerular Apparatus? The juxtaglomerular apparatus is a type of endocrine organ that is small in size, located within kidneys and helps in the regulating the function of nephrons. This is mainly involved in the secretion of renin and EPO in response to changes in the renal blood pressure or blood flow. Juxtaglomerular Apparatus are type of epitheloid cells that are located in the afferent arterioleâs media just at the place where it enters glomeruli. These cells of Juxtaglomerular Apparatus embed secretory granules which are limned on the membrane and constitute renin.
