What structure characteristics of the alveoli make them an ideal site for the diffusion of gases? Why? 2.

Solution

2) These are the structural characteristics of the alveoli are :

i) They have very thin walls

ii) They Provide the lungs with the large surface area

iii) They have a lot of tiny blood vessels called capillaries.

We get oxygen from air and we need to release back waste carbon dioxide. The alveoli are internally designed in such a way that this gas exchange also known as diffusion happens efficiently.
