Simple squamous epithelium is a type of epithelial tissue that comprises of single layered cells that are flat scale shaped or plate like and have contact with the layers of basement membranes of epithelium. It is lined with mesothelium that form surface layer of serous membranes that line body cavities and organs. The simple squamous epithelium are permeable which allow molecules to diffuse readily through itself, it is found in alveoli of lungs, capillaries and kidneys. It also function in absorption and transport of material.
The simple squamous epithelium can be define as the layer of flat cells which can be found in contact with the basal lamina. This layer is permeable to allow the molecules to pass through the membrane for diffusion and filteration.
The diffusion of carbon dioxide and oxygen from the membrane of epithelia is also facilitated by the simple squamous epithelium.
