To allow passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae.
where rapid gas exchange occurs, as oxygen enters the bloodstream through alveolar blood vessels and carbon dioxide exits as waste.
simple squamous. It allows for diffusion.
Simple Squamous Epithelial Tissue forms the surface of the alveoli
the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.
This tissue is simple squamous, a type of epithelium. It is the thinnest tissue, one cell thick, since gases are exchanged in the aleoli and capillaries surrounding them.
Pseudostratified columnar cells line the inside of the trachea and simple squamous cells make up the alveoli

Endothelium is a simple squamous epithelial tissue that lines blood vessels. Mesothelium is a simple squamous epithelial tissue that surrounds the outside of our visceral organs.

Simple Squamous
You can find simple squamous epithelial tissue in alveoli in lungs. The reason of it, is that simple squamous cells are very thin and they pass the gases through very easily. As you know the alveoli's' role is to exchange oxygen and carbon dioxide, thin walls help to do it quicker.
