Buffer system of blood
WebDec 2, 2024 · Human blood has a buffering system to minimize extreme changes in pH. One buffer in blood is based on the presence of HCO 3 − and H 2 CO 3 [H 2 CO 3 is another way to write CO 2 (aq)]. With this buffer present, even if some stomach acid were to find its way directly into the bloodstream, the change in the pH of blood would be minimal. WebPlasma proteins play a limited role in extracellular buffering, whereas intracellular proteins play an important role in the total buffer response of the body. The buffer effect of proteins is the result of their dissociable side groups. For most proteins, including hemoglobin, the most important of these dissociable groups is the imidazole ...
