The bicarbonate buffer system includes carbonic acid and its salt (bicarbonate) and is important in the regulation of the pH of the blood. When strong acids are introduced, they release hydrogen ions (H⁺); however, these ions are quickly tied up by the bicarbonate present in the buffer system, minimizing the change in pH.
