These epithelia are common where absorption or transport of materials is important. They also play a role in diffusion, osmosis and filtration. This makes them important in the kidney, in the alveoli of lungs and in the walls of capillaries.
Since this epithelium is made of a single layer of thin cells that are tightly packed together, it is the ideal medium for selective transmembrane transport. Some substances, such as oxygen from the lungs travel mostly along their concentration gradient towards the blood. Others are actively transported using membrane-bound carrier proteins.
Membrane proteins are involved in forming tight junctions to ensure that the movement of ions, gases, small molecules or water occurs only through the cell and there is no diffusion or osmosis through the interstitial spaces. The rest of the plasma membranes makes up the basolateral surface

Squamous epithelium is made up of thin, flat, polygonal cells.
They are having disc like structure.
The nucleus is rounded, bulging and centrally located.
They form a structure as that of a floor tile .
The squamous epithelium are of two types :
★ Simple Squamous tissue
★ Stratified Squamous tissue
Location :
They form the lining of nose, pericardial cavity, blood vessels, lung alveoli, coelomic cavity etc .
They are also found in the surface of the skin .
Functions :
• Protection
• Exchange of gases
• Ultrafiltration
• Abrasion
