Final answer:
The oral cavity, nasal cavity, and vagina are lined with non-keratinized, stratified squamous epithelium.
Step-by-step explanation:
The oral cavity, nasal cavity, and vagina are lined with non-keratinized, stratified squamous epithelium.
Epithelial tissue is made up of stacked layers of cells and serves to protect against physical and chemical wear and tear. Stratified squamous epithelium is the most common type of stratified epithelium in the human body. The lining of the mouth cavity is an example of non-keratinized stratified squamous epithelium, which provides a tough yet permeable barrier.
