Partial pressures of O2 and CO2 in alveoli is
100 mm Hg and 40 mm Hg respectively
95 mm Hg and 50 mm Hg respectively
104 mm Hg and 40 mm Hg respectively
None of these
As we learnt ,
Partial pressures of these O2 and CO2 in the atmospheric air and the other sites of diffusion -
Alveoli
- wherein
O2 : 104
CO2 :40
