Which of the following options has the correct pair of nephron parts that maintain pH and ionic balance of blood?

Options

A. Proximal convoluted tubule and Henle's loop
B. Distal convoluted tubule and collecting duct
C. Proximal convoluted tubule and glomerulus
D. collecting duct and Henle's loop

Answer

B

Explanation

DCT maintains the pH and ionic balance in the blood by reabsorption of `Na^(+)`, water, `HCO_(3)^(-)` and selective secretion of `H^(+),K^(+)` and `NH_(3)`. Collecting duct plays a role in the maintenance of pH and ionic balance of bloody by reabsorption of water, and elective secretion of `H^(+)` and `K^(+)` ions.
