Final answer:
The esophagus is lined with non-keratinized, stratified squamous epithelium to protect against erosion from food particles.
Step-by-step explanation:
The esophagus is lined by a type of epithelium called non-keratinized, stratified squamous epithelium. This epithelium is chosen specifically for the esophagus because it provides protection against erosion from food particles. The cells of this epithelium are tightly packed together and constantly renew, allowing for effective defense against the abrasive actions of food moving through the esophagus.
