Open in App
Solution
The correct option is D Ducts of Bellini
The macula densa cells of the distal convoluted tubule, the juxtaglomerular cells (or granular cells) of the afferent arteriole along with the extraglomerular mesangial cells (also known as Polkissen cells) are the part of the juxtaglomerular apparatus.
Ducts of Bellini is not a part of the juxtaglomerular apparatus. Many collecting ducts join to form the large duct of Bellini. It represent the most distal portion of the collecting duct system present in the medulla region. These ducts drain all the urine collected from nephron into the renal pelvis.
So, the correct answer is 'Ducts of Bellini'
