Question:

How does tubular secretion help in maintaining ionic and acid-base balance in body fluids?

Answer:

Tubular secretion is also an important step in urine formation. It helps in the maintenance of ionic and acid- base balance of body fluids. During the urine formation substances like K⁺H⁺and ammonia are secreted by tubular cells into the filtrate.

In PCT: Selective secretion of Hydrogen ions, ammonia and potassium take place. PCT helps to maintain the pH and ionic balance of the body fluids.

In DCT: Selective secretion of Hydrogen ions, NH₃ and potassium. It also maintains the pH and sodium- potassium balance in blood.

In Collecting Duct: There is selective secretion of hydrogen and potassium ions. Collecting duct help in maintaining the balance of pH in blood.
