Vedclass · Answer

(B) The $pH$ of human blood is strictly maintained between $7.35$ and $7.45$. This is primarily achieved through the bicarbonate buffer system in the blood. The equilibrium reaction is represented as: $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^+ + HCO_3^-$. The ratio of bicarbonate ions $(HCO_3^-)$ to carbonic acid $(H_2CO_3)$ is critical for buffering excess acids or bases. Therefore, the balance between sodium bicarbonate $(NaHCO_3)$ and carbonic acid $(H_2CO_3)$ acts as the primary buffer system to maintain blood $pH$.
