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 diffusion of oxygen occurs from the alveoli into the blood, whereas the diffusion of carbon dioxide occurs from the blood in the air in the alveoli. The loss of water vapours also occurs from the surface of the alveoli into the lungs. We can observe this condensing while breathing out in cold weather. Inspiration and Expiration WebThe lungs are the gas exchange surface in humans and so are adapted to maximise the exchange of gas by diffusion Inside the lungs there are many rounded alveolar sacs which give a very large surface area to volume ratio These alveoli are highly specialised structures churchill longboards
