Answer:
stratified epithelium
Explanation:
The stratified epithelium is a type of epithelial tissue based on the arrangement of cells in one or more layers. A stratified epithelium consists of two or more layers of cells. These multiple layers of cells protect underlying tissues in regions where there are considerable wear and tear.
For example, stratified squamous epithelium lines the cavity of mouth, esophagus, the surface of tongue whereas the keratinized stratified squamous epithelium is present in the superficial layer of skin. These epithelial layers serve to protect the underlying tissues against abrasion.
