Explanation

Buffering agents are substances that help regulate the pH of body fluids by accepting or releasing hydrogen ions. In the human body, the main buffering systems are the bicarbonate buffer system, the phosphate buffer system, and the protein buffer system. Hemoglobin also acts as a buffer in blood. Carbohydrates, on the other hand, are not considered buffering agents in the body.
