Blood buffering system

The blood buffering system helps maintain a stable pH level in the body, crucial for proper functioning. It mainly involves bicarbonate, proteins, and hemoglobin, which can absorb or release hydrogen ions to counteract acidity or alkalinity. When the body produces excess acids during metabolism, bicarbonate neutralizes them, while respiratory and renal systems support this balance by adjusting carbon dioxide and bicarbonate levels. This dynamic process ensures that the blood remains within a narrow pH range, protecting cells and organs from damage and maintaining overall health.
