How do substances get into, out of and around our bodies?

WebThe fish opens its mouth to let water in, then closes its mouth and forces the water through the gills and out through the operculum (gill cover). This allows for more efficient gas exchange than if the water had to go in and out the same way. This is important for fish becaus of the low oxygen concentration in water. Summary. WebAdaptations of exchange surfaces. For respiration, organisms need to take oxygen into their bodies and remove carbon dioxide.These gases diffuse across exchange surfaces, such as the lungs, so exchange surfaces are adapted to make diffusion as efficient as possible. Most gas exchange surfaces are extremely thin (sometimes just one cell … WebThe diaphragm and rib cage move to create a lower air pressure in the lungs than that of the air outside the body.
