What is the esophagus?

The esophagus is a long hollow tube that starts at the back of your throat and ends at the top of your stomach. When you swallow food or liquids they travel down the esophagus into the stomach. The inner surface of the esophagus is lined with specialized squamous cells that form a barrier to protect the inside of the esophagus. This thin tissue barrier is called the epithelium.
