Question:
How does tubular secretion help in maintaining ionic and acid-base balance in body fluids?
Solution:
Tubular secretion is crucial as it helps in the maintenance of ionic balance in the body fluids.
During urine formation, Proximal Convoluted Tubule maintains the pH and ionic balance of the body fluids by selective secretion. Distal Convoluted Tubule is where
conditional reabsorption of sodium ions and water takes place and maintain the ionic balance and pH. Collecting Duct: From this long duct, large amounts of water could
be reabsorbed to produce concentrated urine.
