Question

65. Which of the following choices correctly traces the route of glomerular filtrate on its path to the collecting duct of a nephron?

Select one:

a. Proximal tubule, Bowman’s capsule, descending loop of Henle, ascending loop of Henle, distal tubule

b. Bowman’s capsule, proximal tubule, descending loop of Henle, ascending loop of Henle, distal tubule

c. Bowman’s capsule, distal tubule, descending loop of Henle, ascending loop of Henle, proximal tubule

d. Bowman’s capsule, proximal tubule, ascending loop of Henle, descending loop of Henle, distal tubule

e. Bowman’s capsule, distal tubule, ascending loop of Henle, proximal tubule, descending loop of Henle

Answer 1

ANS. 65. The correct choice that traces the route of glomerular filterate on its path to the collecting duct of a nephron is

b. Bowman’s capsule, proximal tubule, descending loop of Henle, ascending loop of Henle, distal tubule.

Explanation - The renal tubule starts with Bowman's capsule. Bowman's capsule is a cup shaped double-walled structure. It encloses a mesh like structure called glomerulus. Then the tubule continues to form PCT i.e. proximal convoluted tubule which goes downward and upward, and known as descending loop of henle and ascending loop of henle respectively. The ascending limb of Henle then continues to another tubular region known as DCT i.e. distal convoluted tubule.
