The part of nephron involved in conditional reabsorption of sodium is

A
Distal convoluted tubule
Correct answer
B
Proximal convoluted tubule
C
Bowman's capsule
D
Descending limb of Henle's loop

Solution

Conditional reabsorption of Na⁺and water takes place in the DCT segment. DCT is also capable of reabsorption of HCO₃^- and selective secretion of hydrogen and potassium ions and NH₃ to maintain the pH and sodium-potassium balance in the blood.

Hence, the correct answer is option: 'B'.
