Buffers in the blood work to maintain a stable pH level by accepting excess H+ ions if the blood becomes too acidic or releasing H+ ions if the blood becomes too basic. This helps to keep the pH of the blood within a narrow range and prevent the blood from becoming too acidic as carbon dioxide is transported to the lungs.
