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
Simple Squamous
Epithelial tissue can be subdivided into two main types: simple and stratified. Squamous epithelial tissue is characterized by its flat, scale-like cells, which can be found in areas where diffusion or filtration occurs, such as the alveoli of the lungs and the lining of blood vessels. Simple squamous epithelium consists of a single layer of these flat cells, while stratified squamous epithelium has multiple layers, providing protection in areas subject to abrasion, like the skin and the lining of the mouth.
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.

Epithelial tissue is found in various organs throughout the body, serving as a protective layer and facilitating functions such as absorption and secretion. Examples of organs with epithelial tissue include the skin, which has stratified squamous epithelium, and the intestines, lined with simple columnar epithelium for nutrient absorption. Additionally, the lungs feature simple squamous epithelium in the alveoli to facilitate gas exchange. Overall, epithelial tissue is crucial for the structure and function of many organs.
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.
