How do alveoli make gas exchange efficiency
WebOct 29, 2024 · Alveoli Gas Exchange The alveoli and capillaries share a membrane, so gases like oxygen and carbon dioxide can move freely from the alveoli into the capillaries and from the capillaries into the alveoli. When you breathe … WebJan 17, 2024 · As the alveoli fill with air during inhalation they expand, and as air leaves the lung with exhalation, the alvoli return to their non-inflated size. The reason for the elasticity of the alveoli is a protein found in the extracellular matrix of the alveoli, called elastin, as well as the surface tension of water molecules on the alveoli themselves.
