Yes, the pH of the blood is controlled by the bicarbonate buffer system: CO₂ (g) + H₂O (l) ⇌ H₂CO₃ (aq) ⇌ H⁺ (aq) + HCO₃⁻ (aq) If the concentration of CO₂ temporarily gets too high, the ability of the buffer to control pH may be temporarily overloaded. Fortunately, too much CO₂ in the blood triggers a reflex ...

"WebHuman 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. " - Phosphoric acid buffer system in the blood
