For plants see Transport in plants BUT first read Diffusion, osmosis and active transport then this page Sub-index for these pages on exchange surfaces in organisms 2. Introduction to exchange surfaces in cells and organs 3. Gas exchange in the human lungs by diffusion, comments on breathing, COPD and ventilators 4. Gas exchange and the structure of fish gills 5. The function of villi in the exchange surface of the small intestine 6. Exchanges surface structure adaptations in other animals See also The human circulatory system - heart, lungs, blood, blood vessels
