d) |
All of the above |
(d)
All of these.
Alveoli are the primary site of exchange of gases. Exchange of gases also occur between the blood and tissue. 
and 
are exchanged in these sites by simple diffusion, mainly based on pressure concentration gradient
Pressure/Concentration gradient, solubility of gases as well as the thickness of the membranes involved in diffusion are some important factors that affects the rate of diffusion
