Alveoli have the job of gas exchange. So what things influence gas exchange - from your knowledge of chemistry?
I'll give you two hints:
Surface area
Distance for the gas(es) to diffuse.
Have a look at the structure of an alveolus from your textbook and see if you can relate the structure of an alveoli with the function, given the hints I've given you above.

think about thin walls, high surface area, amount of blood flow and moistness etc. you can always look at an exam question and look at the ms for any more help

- 1 cell thick therefore short diffusion distance for oxygen
- Million of alveoli all of the body therefore high SA meaning higher vol of oxygen present for the body
- Surrounded by surfactant fluid meaning that oxygen diffuses into the fluid then into blood, providing an easier diffusion pathway

The walls of the alveoli are one cell thick (short diffusion distance).
There are many alveoli, proving a large surface area for gas exchange.
The walls of the alveoli are elastic, and expand during inspiration, increasing the surface area for gas exchange.
The walls of the alveoli are elastic, and recoil during expiration, removing carbon dioxide out of the lungs passively.
