A group of nursing students are studying for a test over acid-base imbalance. One student asks another what the major chemical regulator of plasma pH is. What should the second student respond?

Question

Quizplus · Accepted Answer

The major chemical regulator of plasma pH is the bicarbonate-carbonic acid buffer system, which involves the conversion of carbon dioxide to bicarbonate and back again. This buffer system helps to maintain a stable pH in the blood by absorbing or releasing hydrogen ions as necessary. The other options (A, C, D) are not directly involved in acid-base regulation.
