MICROANATOMY

Detailed explanation-1: -The squamous epithelium is made of a single thin layer of flattened cells with irregular boundaries. They are found in the walls of blood vessels and air sacs of lungs. Due to their single thin layer, they are involved in a functions like forming a diffusion boundary.

Detailed explanation-2: -Simple squamous epithelial cells are thin and flat (the thinnest of all epithelial cell-types), which allows them to have a large surface area that is exposed to the lumen on one side (the apical surface), and to the basement membrane (i.e. basal lamina) on the other (the basolateral surface; Figure 1).

Detailed explanation-3: -Simple squamous epithelium – a single layer of thin flattened cells. This type of epithelium forms thin delicate sheets of cells through which molecules can easily pass (diffusion, filtration).

Detailed explanation-4: -Squamous cells are thin and flat, just like the scales after which they are named. They provide a smooth surface that avoids blood turbulence in the blood vessels and also allows fluids to easily flow over them.
