The Mechanism Used by the Body to Regulate Body PH

Question

The mechanism used by the body to regulate body pH is
A) the buffer system
B) the respiratory mechanism
C) the urinary mechanism
D) all of the above

Accepted Answer

The body uses all three mechanisms, i.e., buffer system, respiratory mechanism, and urinary mechanism, to regulate body pH. The buffer system provides the immediate response to changes in pH, the respiratory mechanism adjusts the levels of carbon dioxide in the blood, while the urinary mechanism excretes excess acids or bases from the body. Therefore, option D, i.e., all of the above, is the best choice.
