Quizplus · Accepted Answer

Chemical buffer systems can act within a fraction of a second to buffer changes in [H⁺], thereby helping to maintain pH homeostasis within the body. However, they are not the only mechanism available for regulating changes in pH, as the respiratory and renal systems also play important roles in pH regulation. Buffer systems do not eliminate acid or bicarbonate from the body, but rather help to prevent excessive changes in their concentrations.
