- Esophagus
- The esophagus, part of the digestive tract, is a tube that connects the throat with the stomach. It lies between the trachea (windpipe) and the spine. In an adult, the esophagus is about 10 inches long. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and makes swallowing easier. It is commonly referred to as the "gullet."
* * *The portion of the digestive canal between the pharynx and stomach. It is about 25 cm long and consists of three parts: the cervical part, from the cricoid cartilage to the thoracic inlet; the thoracic part, from the thoracic inlet to the diaphragm; and the abdominal part, below the diaphragm to the cardiac opening of the stomach. [G. oisophagos, gullet]
