Chemical buffer systems can act within a fraction of a second to buffer changes in [H+]. They work by either donating or accepting protons to maintain the pH level within a narrow range. Although they are an important mechanism for regulating changes in [H+], they are not the only mechanism available. The respiratory system and the kidneys also play a role in regulating acid-base balance in the body. Chemical buffer systems do not eliminate acid or bicarbonate from the body, but rather help to maintain their balance.
