Final answer:
The outermost layer of the skin is composed of stratified squamous epithelium.
Step-by-step explanation:
The outermost layer of the skin is composed of stratified squamous epithelium. Epithelial tissues cover the outside of organs and structures in the body and line the lumens of organs in a single layer or multiple layers of cells. The types of epithelia are classified by the shapes of cells present and the number of layers of cells.
Epithelia composed of a single layer of cells is called simple epithelia; epithelial tissue composed of multiple layers is called stratified epithelia. The outermost layer of our skin is composed of dead stratified squamous, keratinized epithelial cells.
