Final answer:
Stratified squamous epithelium has two main functions: protection and replaceability.
Step-by-step explanation:
Stratified squamous epithelium is a tissue that consists of multiple layers of cells with the most apical being flat scale-like cells, and it functions to protect surfaces from abrasion. There are two main functions of stratified squamous epithelium:
- Protection: The multiple layers of cells in stratified squamous epithelium provide a barrier that protects underlying tissues from mechanical stress and abrasion. The flat scale-like shape of the apical cells helps to minimize damage from friction.
- Replaceability: The cells in the outermost layer of stratified squamous epithelium can be easily shed and replaced. This ensures that the tissue remains intact and functional even if superficial damage occurs.
