Oxygen is trаnsferred frоm аlveоlаr gas intо the blood via simple diffusion across the epithelial layers that line the lungs and the adjoining capillaries.The rate of diffusion, J = D (C1-C2)/X.D = diffusion coefficient, C = concentration, X = the distance between the two concentrations.If, as the result of lung cancer, the total thickness of these layers doubles AND the combined diffusion co-efficient for these layers halves, the rate at which oxygen will diffuse from alveolar gas into the blood will be:
