Unformatted text preview: bicarbonate ion reacts with H+ to create is conjugate acid and water. In our bodies, exercise increases the concentration of H+ and CO 2 and this mechanism above is utilized when we exercise (blood cells exchange oxygen for carbon dioxide and protons in the muscles). These mechanisms will try to stabilize the pH to normal by lowering it as quickly as possible. However, a high heart rate (which comes along with exercise) does not benefit us for it hinders CO 2 removal and keeps our bodies at unsafe pH levels. To cope with stress, the body uses the lungs to remove excess CO 2 and the kidneys remove excess HCO 3-. In summation, our body has been evolutionally tweaked for millions of years so that systems such as homeostasis and buffers are refined and improved so that they work for us as flawlessly as possible....
