Gas exchange in the lung. When you inhale oxygen, it enters the lungs and travels to the alveoli. Cells lining alveoli and capillaries carrying blood are in close contact with each other. The barrier thickness averages to 1 micron - that’s 1/10 000 of a centimetre!

WebMay 14, 2024 · Their lungs are considerably more efficient than those of amphibians. They have a much greater surface area for the exchange of gases. They are inflated and deflated by the bellowslike expansion and contraction of the rib cage. WebThe gas exchange surfaces are the alveoli. They are very efficient at gas exchange. They provide a large surface area relative to the volume of the body; Gasses dissolve in the surfactant moisture lining the alveoli; The alveoli have walls made of squamous epithelium, only one cell thick, so the diffusion pathway for gases is short
