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

In the lung alveoli, where there is high partial pressure of oxygen$\left({\text{pO}}_2\right)$, low${\text{pCO}}_2$, lesser${\text{H}}^{+}$ion concentration$\left(\text{high pH}\right)$and lower temperature are all favourable factors to promote binding of oxygen with haemoglobin to form oxyhaemoglobin at the time of external respiration.
