Traveling from the alveoli to capillary blood, gases must pass through alveolar surfactant, alveolar epithelium, basement membrane, and capillary endothelium. According to Fick’s law of diffusion, diffusion of a gas across the alveolar membrane increases with:

Fick
WebFick's laws of diffusion states that the rate at which a molecule moves through a material is proportional to the concentration gradient (the difference in concentrations) between the two ends of the material; and … WebFick’s law of diffusion states that gas transfer across a membrane is directly proportional to the concentration gradient. Graham’s law states that diffusion of a gas is inversely proportional to the square root of the molecular weight of the molecule. Other factors which increase diffusion: • Large surface area • Thin membrane WebFick's laws of diffusion describe diffusion and were derived by Adolf Fick in 1855. They can be used to solve for the diffusion coefficient, D.Fick's first law can be used to derive his second law which in turn is identical to the diffusion equation..
