Zoology - Breathing and Exchange of Gases Question with Solution | TestHub

To maximize exchange of${\mathrm{O}}_2$with$\mathrm{C}{\mathrm{O}}_2$, the tissues have low partial pressure for oxygen and high partial pressure for carbon dioxide. Also, to fa cilitate dissociation of oxyhaemoglobin the hydrogen ion concentration is on the higher side as it discourages binding of Hb to${\mathrm{O}}_2$.
