Q. Partial pressure of $O_{2}$ and $CO_{2}$ in atmospheric airs compared to those in alveolar air is $\rho O_{2}$ $\rho CO_{2}$

A) Higher Lower
B) Higher Higher
C) Lower Lower
D) Lower Higher
Explanation

Partial pressure of $O_{2}$ is higher in atmosphere as compared to the alveolar air. Due to this pressure gradient, $O_{2}$ goes inside the body and same phenomena happens in case of $CO_{2}$ but in opposite direction
