To allow passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae.
simple squamous. It allows for diffusion.
Simple Squamous Epithelial Tissue forms the surface of the alveoli
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.
the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.
Pseudostratified columnar cells line the inside of the trachea and simple squamous cells make up the alveoli

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.
No, stratified squamous epithelium is not the body's most delicate epithelial tissue. It is actually one of the tougher epithelial tissues in the body, providing protection against mechanical stresses and abrasions. Simple squamous epithelium, found in tissues like the alveoli of the lungs, is much thinner and more delicate.
