High percentage of $CO_{2}$ is transported in dissolved form as compared to $O_{2}$. This is because

Although much $CO_2$ is carried in the blood,yet blood does not become acidic. This is because

The $Hamburger$ shift is also known as which of the following?

Which factors affect the dissociation of $O_{2}$ from $Hb$?

$CO_{2}$ diffuses into ...$A$... and forms $HCO_{3}^{-}$ and $H^{+}$. At the ...$B$... site where $pCO_{2}$ is low, the reaction proceeds in the opposite direction.
Thus, $CO_{2}$ is trapped as ...$C$... at the tissue level and transported to alveoli is released out as ...$D$...
Select the right choice for $A, B, C$ and $D$ to complete the given $NCERT$ statement.
