What will be the pO2 and pCO2 in the atmospheric air compared to those in the alveolar air? (i) pO2 lesser, pCO2higher (ii) pO2 higher, pCO2lesser (iii) pO2 higher, pCO2 higher (iv) pO2 lesser, pCO2lesser
(ii) pO2 higher, pCO2 lesser pO2 higher will create the pressure gradient to facilitate the movement of O2 from atmosphere to alveoli and pCO2 lesser will create the movement of CO2 from alveoli to atmosphere.
