Right answer is (ii) pO2 higher, pCO2 lesser
The partial pressure of oxygen in atmospheric air tends to be more than the partial pressure of oxygen in alveolar air. In atmospheric air, the pO2 is approximately 159 mm Hg. In alveolar air, it's approximately 104 mm Hg. The partial pressure of CO2 in atmospheric air is lower. as CO2 within the alveolar air. In atmospheric air, the pCO2 is around 0.3 mmHg. In alveolar air, it's about 40 mm Hg.
