<P> 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 . 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 , outer layer of skin and other tissues where rapid diffusion is required . Cells are flat with flattened and oblong nucleus . It is also called pavement epithelium due to its tile - like appearance . This epithelium is associated with filtration and diffusion. This tissue is extremely thin , and forms a delicate lining . It offers very little protection . </P>
