Identify the organ.

Recognizing organ identity from epithelial lining helps you identify the esophagus. It is lined by non-keratinized stratified squamous epithelium, which provides protection against abrasion as food moves down the throat. Beneath this, you may see a muscularis mucosae and often submucosal mucous glands. This contrast with the other options: the stomach has simple columnar epithelium with gastric pits and rugae; the small intestine shows villi and crypts of Lieberkühn with absorptive enterocytes; the colon has a simple columnar lining with many goblet cells but no villi. These features point to the esophagus as the correct organ.
