WebJan 17, 2024 · External respiration is the formal term for gas exchange. It describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion. While the bulk flow of air from the external environment happens due to pressure changes in the lungs, the mechanisms of alveolar … WebOf particular importance to plants is the ability of a large, multicellular organism to move materials throughout the organism, a process that is accomplished by a combination of diffusion and pressure flow. TOPICS. Diffusion. A simple but insufficient model. Osmosis — the diffusion of solvents, including water.
WebMovement Across a Membrane and Energy. There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used.
