Question

The glomerulus is a network of parallel capillaries which are approximately ........... in number.

• A. 5
• B. 50
• C. 500
• D. 5000

Answer 1

The correct option is B 50

Each kidney receives its blood supply via single renal artery from dorsal aorta and is drained off via a single renal vein, which opens in the inferior vena cava. As the artery enters into the medulla after traveling through the hilum, it divides into a number of branches. These branches enter into renal cortex through the column of Bertin and subdivide into afferent arterioles, which form glomerular capillaries. The glomerulus consists of a network of about 50 capillaries. Therefore, the correct answer is option B.
