Textbook Problem

The major substance(s) transported by means of tubular secretion is (are)

1 . H + 2 . Cl - 3 . K + 4 . HCO 3 5 . Na +

A. 1 only

B. 2 and 4 only

C. 4 and 5 only

D. 1 and 3 only

Summary Introduction


Tubular secretion is the process in which substances from the plasma are transported to the renal tubule. It works in the direction opposite to the one in which tubular reabsorption works. It is an additional mechanism that provides entry to the plasma fluid into the tubules.


Explanation/justification for the correct answer:

Option (d) is given as 1 and 3 only. In the process of tubular secretion, some substances will be removed from the blood and added to the fluid in the collecting ducts, which are removed to maintain the volume and composition of blood. The major substances transported by way of tubular secretion are H+ and K+ for osmoregulation. So, option (d) is correct.

Explanation for the incorrect answer:

Option (a) is given as 1 only, that is, hydrogen ions only. However, tubular secretion is responsible for the transport of hydrogen as well as potassium ions...
