Stratified epithelium is a type of tissue composed of multiple layers of cells. This structure provides added protection, making it ideal for areas of the body that experience friction or abrasion, such as the skin and the lining of the mouth. The outermost layer is made up of flat cells, while deeper layers can vary in shape. There are different types of stratified epithelium, including stratified squamous epithelium, stratified cuboidal epithelium, and stratified columnar epithelium. Each type serves specific functions and is found in various locations throughout the body, contributing to overall health and protection.
