Final answer:
The stratified squamous epithelium is made up of multiple layers of cells to protect underlying tissues from abrasion and damage. The surface squamous cells can be shed and replaced from the deeper layers, providing durability and resilience. This epithelial tissue is found in the skin and lining of the mouth and vagina.
Step-by-step explanation:
The stratified squamous epithelium is characterized by multiple layers of cells, with the surface layer being composed of flat, scale-like cells known as squamous cells. This arrangement provides a protective barrier against abrasion, physical damage, and pathogen entry. The layers are stacked in a way that allows the outermost cells, which often endure the most wear and tear, to be periodically shed and replaced by cells from the deeper layers.
This epithelial tissue is commonly found in areas of the body that require a high degree of protection, such as the skin, and linings of the mouth and vagina. In some locations, like the skin, the top layers are keratinized with dead cells to further augment protection. In other areas such as the mouth, the epithelium remains unkeratinized, retaining living cells that offer flexibility and moisture.
