WebAdaptations of the Alveoli The 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 WebAlveoli have features that speed up the rate of diffusion so that gases can be exchanged quicly. They have a thin exchange surface - the alevolar epithelium is only one cell thick, which means there's a short diffusion pathway, which speeds up diffusion. The alevoli also have a large surface area - the large number of alevoli means there's a ...
