Assertion: PCT, DCT and collecting duct helps in the maintenance of pH and ionic balance of blood by the selective secretion of `H^(+)` and `K^(+)` ions. 
Reason: PCT and DCT, both are capable of reabsorbing `HCO_(3)^(-)`ion

Maintenance of pH and ionic balance of blood takes place by the selective secretion of certain ions takes place in

Maintenance of pH and ionic balance of blood takes place by the selective secretion of certain ions takes place in PCT DCT Collecting duct All the above

Assertion: DCT and collecting duct maintain the pH and ionic balance of blood. Reason: DCTs of many nephrons open into a collecting duct.

Which of the following function is performed by collecting tubule of kidney? (A) In the maintenance of pH and ionic balance of blood by the secretion of H^(+) and K^(+) ions (B) Maintenance of pH of blood and removal of Na^(+) and K^(+) ions (C) Absorption of glucose and ammonia from the blond (D) None of above

Which of the following statements is/are incorrect regarding the collecting duct? (i). It extends from the cortex to medulla. (ii). Large amount of water could be reabsorbed by it to produce concentrated urine. (iii). Small amount of urea diffuses into it from the medulla to keep up the osmolarity. (iv). it plays a role in maintaining pH and ionic balance of blood by the selective secretion of H^(+) and K^(+) ions.

Assertion :- Conditional reabsorption of Na^(o+) and water takes place in DCT. Reason :- DCT is also capacble of selective secretion of hydrogen and potassium ions.
