Q. Blood do not become acidic although it carries $CO_{2}$ because
A) $CO_{2}$ is continuously diffused though tissues
B) $CO_{2}$ combines with $H_{2}O$ to form $H_{2}CO_{3}$
C) In $CO_{2}$ transport, buffers plays an important role
D) $CO_{2}$ is absorbed by WBC
Explanation
Blood do not become acidic due to the buffering action of bicarbonates $H_{2}O + CO_{2} \rightleftharpoons H_{2}CO_{3} \rightleftharpoons H^{+} + HCO_{3}^{-}$
