Both statements are true.

Vedclass · Answer

(B) Statement-$I$ is true: The factors favourable for the diffusion of gases include the partial pressure gradient,the thickness of the membranes involved in diffusion,and the solubility of the gases. In the alveoli,the partial pressure of $O_2$ $(pO_2)$ is high,which facilitates its diffusion into the blood and subsequently to the tissues. Conversely,the partial pressure of $CO_2$ $(pCO_2)$ is higher in the tissues,which facilitates its diffusion into the blood and then to the alveoli.Statement-$II$ is true: When the percentage saturation of haemoglobin with $O_2$ is plotted against the $pO_2$,the resulting curve is '$S$' shaped,which is known as the 'Oxygen dissociation curve' or 'Sigmoid curve'.

Statement-$I$: All the factors in our body are favourable for the diffusion of $O_2$ from alveoli to tissues and that of $CO_2$ from tissues to alveoli.
Statement-$II$: $A$ sigmoid curve is obtained when the percentage saturation of haemoglobin with $O_2$ is plotted against the $pO_2$.
