Solution:

Simple squamous epithelia consist of a single layer of flattened cells in contact with the basal lamina. This type of epithelial lines the inner surface of all blood vessels (endothelium), forms the wall of alveolar sacs in the lung and lines the body cavities (mesothelium). This type of epithelium is often permeable and occurs where small molecules need to pass quickly through membranes via filtration or diffusion.
