The single most important blood buffer system is the bicarbonate buffer system.

Question

Quizplus · Accepted Answer

The bicarbonate buffer system is the most important blood buffer system as it helps to maintain the pH balance in the blood by removing excess hydrogen ions (acid) or adding hydrogen ions (base) as needed. It involves the conversion of carbon dioxide and water into carbonic acid, which is then converted into bicarbonate ions and hydrogen ions. The bicarbonate ions act as a base to neutralize excess hydrogen ions, while the hydrogen ions combine with hemoglobin to reduce their acidity. This system plays a crucial role in regulating the pH of the blood, as even small changes in blood pH can have serious physiological effects.
