Oesophagus

The oesophagus connects the mouth and throat cavity with the stomach; it begins at the height of the larynx (trachea starts at larynx), continues down the posterior thoracic cavity and, after passing through the diaphragm (hiatus oesophageus), leads into the stomach in the abdomen. It is a 25-cm-long muscular tube that is lined on the inside with plaque or plaster epithelium and it transports the swallowed food to the following digestive organs.
