How does the Juxtaglomerular apparatus regulate filtration rate?

It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus. The juxtaglomerular cells, derived from smooth muscle cells, of the afferent arteriole secrete renin when blood pressure in the arteriole falls.Click to see full answer. Keeping this in consideration, what makes up the Juxtaglomerular apparatus?The juxtaglomerular apparatus (see Fig. 1.5) comprises the macula densa, the extraglomerular mesangium, the terminal portion of the afferent arteriole with its renin-producing granular cells (nowadays also often termed juxtaglomerular cells), and the beginning portions of the efferent arteriole. The macula densa (Fig.Subsequently, question is, what part of the nephron forms the Juxtaglomerular apparatus? The juxtaglomerular apparatus is part of the kidney nephron, next to the glomerulus. It is found between afferent arteriole and the distal convoluted tubule of the same nephron. This location is critical to its function in regulating renal blood flow and glomerular filtration rate. Keeping this in consideration, what does the Juxtaglomerular apparatus monitor? Urinary System: Juxtaglomerular complex The afferent arteriole in this region contains specialised secretory cells (smooth muscle cells) called juxtaglomerular cells, that secrete renin. These cells do two things: They monitor blood pressure, by measuring how much the arteriole wall is stretched.Which is true about the Juxtaglomerular apparatus?A) It is created by the junction between the proximal tubule and the afferent arteriole. It is composed of parts of the ascending limb of the loop of Henle and the efferent arteriole. C) It is the site of renin secretion.
