Do alveoli have very thick walls?
No, alveoli do not have very thick walls. In fact, they have very thin walls composed of a single layer of epithelial cells, which facilitates efficient gas exchange between the air in the alveoli and the blood in the surrounding capillaries. This thin structure allows oxygen to diffuse into the blood and carbon dioxide to diffuse out easily.
Why are the walls of the alveoli one cell thick?
The reason for this is that oxygen and carbon dioxide need to diffuse through this membrane very quickly to re-oxygenate the blood. The thicker the barrier, the longer the process, and since breathing is rather rapid it needs to happen fast.
How thick are the walls of alveoli?
The walls of alveoli are extremely thin, typically measuring about 0.2 to 0.5 micrometers in thickness. This thinness is crucial for efficient gas exchange, allowing oxygen and carbon dioxide to diffuse easily between the alveoli and the surrounding capillaries. The alveolar walls are composed of a single layer of epithelial cells, which further facilitates this process.

Fudi
Why does the walls of the capillaries and the alveoli have to be thin?
If their walls are too thick, substances like oxygen and nutrients and waste cannot pass across the cells into or out of the body.
