How do alveoli make gas exchange efficiency
WebGas exchange by direct diffusion across surface membranes is efficient for organisms less than 1 mm in diameter. In simple organisms, such as cnidarians and flatworms, every cell in the body is close to the external environment. Their cells are kept moist and gases diffuse quickly via direct diffusion. WebSep 13, 2024 · Accordingly, perfluorocarbons make highly suitable agents for filling alveoli, as they will generally not impede gas exchange Pulmonary surfactants are mixtures of lipids and proteins that are secreted into the alveolar space by alveolar cells to decrease the surface tension between the air/liquid interfaces in the lung.
