What is the function of this tissue?
The shape of the nuclei of the surface cells in this type of epithelium is squamous, which means they are flat and disc-like.
The nuclei of cells deeper in the epithelium can be either cuboidal or columnar, depending on the specific layer they are in.
This type of tissue is found in various areas of the body, including the skin, mouth, esophagus, and blood vessels.
The function of this tissue is to provide protection, as the multiple layers help to prevent damage and provide a barrier against pathogens and other harmful substances. Additionally, the squamous shape of the cells allows for easy diffusion and absorption of substances.
