What is composed of several layers of flattened cells and is found in the skin?

The tissue composed of several layers of flattened cells found in the skin is called stratified squamous epithelium. This type of epithelium provides protection against abrasion, pathogens, and water loss. It is primarily located in the outer layer of the skin (epidermis), where the cells continually shed and are replaced. Stratified squamous epithelium can be either keratinized, as seen in the skin, or non-keratinized, found in areas like the oral cavity and esophagus.
