Esophagus: The Muscular Tube Connecting Mouth to Stomach

The tube that carries food from the mouth to the stomach is called the esophagus. The esophagus is a muscular tube that connects the throat to the stomach. When you swallow, the muscles of the esophagus contract and relax, propelling the food down to the stomach. The esophagus is lined with mucus that helps to protect it from the acidic contents of the stomach.
