This is just a one line question.

→The pO2 and pCO2 in the atmospheric air compared to those in the alveolar air is pO2 higher, pCO2 lesser.

★Why pO2 is more??

→That's because of the more amount or percentage of O2 in air than in alveoli.

★Why pCO2 is less??

→That's because of the various activities taking place inside the body and releasing of CO2 in the body.
