I think the 4 main points are
1) large surface area so more substances can diffuse at once
2) moist lining around the alveolus means that gases can be dissolved before diffusion
3) there is a really good blood supply (a lot of capillaries) this means that there is a larger concentration gradient so more gases diffuse faster making it more efficient
4) the cell wall is really thin (I think it’s only one cell thick) so this means there is a shorter diffusion pathway for the substances to diffuse through

I think that’s it and I hope that helped!
