Features of gas exchange surfaces
- Have a large surface area relative to the volume of the organism.
- They are thin, so have a short diffusion pathway.
- They have a moist surface where gases can dissolve first before they diffuse in our out.
- They are able to maintain the diffusion gradient down which the gases can diffuse.

∙ 11y ago1) Thin walls-more rapid diffusion
2)Large surface area-increase the rate of diffusion
3)Moist-O2 dissolves better in water, diffuse efficiently
4)Blood flowing in one direction
