Squamous cells in the esophagus form a protective barrier against mechanical and chemical damage caused by food and liquids passing through. They help in preventing infections and inflammation. The squamous cells in the esophagus also play a role in the process of swallowing by aiding in the smooth passage of food and liquids.
