The eosophagus/esophagus (or gullet) is a long, muscular tube that connects the throat, specifically the pharynx, with the stomach. The eosophagus is located between the trachea (windpipe) and spine.
The eosophagus moves food down by a contraction and release pattern called peristalsis. This peristalsis action allows the swallowed food to be moved into the stomach for digestion. Since the eosophagus is lined with glands that produce mucous, the whole tube is always moistened and this assists with swallowing and peristalsis.
- In adults, the eosophagus is about 25cm (10 inches) long
- Heartburn (acid reflux) is caused by stomach acid refluxing or splashing up into the esophagus
Why the eosophagus is important
There are several layers of tissue that make up the eosophagus - which makes up its strength and enables the effective peristalsis action that it performs on a daily basis.
