Where Is Simple Squamous Epithelium Found In The Body
Camila Farah
A simple squamous epithelium is a single layer of flat cells in contact with the basal lamina one of the two layers of the basement membrane of the epithelium.
Due to its single layer of cells this thin tissue is not designed well for protection. This type of epithelium is often permeable and occurs where small molecules need to pass quickly through membranes via filtration or diffusion simple squamous epithelia are found in capillaries alveoli glomeruli and other tissues. Epithelia are tissues consisting of cells closely juxtaposed without intervening intercellular substances. This epithelial type is found in the walls of capillaries linings of the pericardium and the linings of the alveoli of the lungs.
One side of the surface opens to the environment while the other is anchored to the underlying cells. Some cells in the simple squamous epithelium are also known to produce some fluids like the mucus that acts as a lubricating agent against the inevitable friction. The squamous epithelial cells are thin flat cells found in layers or sheets that cover surfaces such as the skin and the lining of blood vessels and the esophagus. The simple squamous epithelium forming the mesothelium facilitated the movement of the viscera and the active transport of fluid by the process of pinocytosis.
Generally this type of epithelium is found inside the body probably due to the fragile nature and forms the lining of the body cavities blood and lymph vessels heart and respiratory system. These cells provide a thin membrane that allows for the passage of small molecules into the body. Epithelia are avascular but all epithelia grow in an underlying layer of vascular connective tissue. Simple squamous epithelium refers to a single layer of thin flat cells that line body surfaces.

Simple squamous epithelia are found both in alveoli and capillaries and their flat thin single layered structure is important for the exchange of gases between the lungs and blood. The squamous cells are thin large and flat and consisting of around nucleus. Cuboidal squamous and columnar. One would need to add layers of cells stratified squamous epithelium to increase its protective properties.
Simple squamous epithelium cells are flat in shape and arranged in a single layer. Being a thin layer has the physiological advantage of faster absorption and.
