Final answer:
The bicarbonate buffer system is crucial for regulating pH balance and preventing drastic changes in the body's acidity levels.
Explanation:
Bicarbonate buffer system is the primary buffering system in the body that helps maintain pH balance. It involves the conversion of carbon dioxide into carbonic acid and bicarbonate (HCO3-) ions to regulate pH levels. This system prevents drastic changes in pH by absorbing excess hydrogen or hydroxyl ions, essential for maintaining homeostasis.
