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.
