Esophagus
The esophagus connects the nose and mouth with the stomach. The epiglottis folds over the trachea when a swallow occurs, to prevent the swallowed substance from being inhaled into the lungs. When a person is unable to swallow because of illness or coma, a tube may be inserted either through the mouth or nose, past the epiglottis, into the esophagus and into the stomach. Nutrients will be passed through the tube directly into the stomach.
