Question

suggest why alveoli have thin walls?

Answer 1

Alveolar walls are thin because they are the main place in the lungs for oxygen and carbon dioxide to be exchanged.

Gas exchange in the lungs happens in the alveoli . Some of the features of alveoli include: thin walls (just one cell thick) to reduce the diffusion distance. ... moist surface for the dissolving of gases in alveolar air so that they can diffuse across the alveolar walls.
