Esophagus • muscular tube whose function is to transport food from the mouth to the stomach. • It is lined by non keratinized stratified squamous epithelium. • In general, the esophagus has the same major layers as the rest of the digestive tract.
In the submucosa are groups of small mucus-secreting glands, the esophageal glands, secretions of which facilitate the transport of foodstuffs and protect the mucosa. • In the lamina propria of the region near the stomach are groups of glands, the esophageal cardiac glands, which also secrete mucus.
