GASEOUS EXCHANGE & FACTORS DETERMINING Q. 1 CO2 diffuses more easily through the respiratory membrane than 02 because it is: A Less dense B More soluble in plasma C Less molecular weight D Less PCO2 in the alveoli Q. 1 CO2 diffuses more easily through the respiratory membrane than 02 because it is: A Less […]

GASEOUS EXCHANGE & FACTORS DETERMINING GASEOUS EXCHANGE & FACTORS DETERMINING Diffusion of gases from alveoli to blood (O2) or from blood to alveoli (CO2), happens via alveolocapillary (respiratory) membrane. This is gaseous exchange process. Factors affecting gasous diffusion: 1. Thickness of respiratory membrane: Normal thickness – 0.5 µm, Thickening of membrane seen in: Pneumonia, TB,
