WebProduction of such acids during peak exercise can lower peripheral blood pH to well below 7.0. The bicarbonate buffering system is central to pH regulation in human blood and can respond to pH changes in several ways: The bicarbonate ion is really the conjugate base of carbonic acid: H + + HCO 3- [H 2 CO 3] ; pKa = 6.14. WebThe pH of blood plasma is maintained at about 7.40 by several buffer systems, the most important of which is the HCO3/H2CO3 system. In the erythrocyte, where the pH is 7.25, the principal buffer systems are HCO3/H2CO3 and hemoglobin.
