WebThe thickness of the alveolar-capillary barrier varies from 0.2 to 2.5 µm. The wall of the capillary endothelial cell is fused to that of the alveolar cell with only a very thin basement membrane between these two cells. This produces a very narrow gap across which oxygen and carbon dioxide can rapidly diffuse.
