Question

How do alveoli adapt to their function?

Answer 1

Alveoli:

Alveoli are tiny air sacs present in the lungs that aid in the transport and exchange of gases.

Adaptation of alveoli:

1. The alveoli present in the lungs have thin walls composed only of a single layer of cells in order to minimize the diffusion distance.
2. Their walls are moist which helps the gases to diffuse better.
3. They are richly supplied with blood capillaries to ensure the efficient exchange of gases with the bloodstream.
4. It maintains a high diffusion gradient to aid the incorporation of oxygen into blood and simultaneously remove carbon dioxide.
