  • Factors affecting diffusion
    • permeability of the alveoli and capillary cell walls
    • short distance from alveoli to capillary
    • readiness of haemoglobin to combine with oxygen - oxyhaemoglobin
    • diffusion gradient  caused by different partial pressures of the gases involved
    • large surface are of alveoli
    • moisture layer enhancing the uptake of oxygen
