Definition:Tube that connects the pharynx to the stomach. In mammals, the oesophagus connects the buccal cavity with the stomach. The stratified squamous non-keratinised epithelium lining the buccal cavity is continued through the pharynx down into the oesophagus. The lowest part of the oesophagus (ca. 2 cm) is lined with gastric mucosa and covered by peritoneum. The main body of the oesophagus is lined with small, simple mucous glands. Each gland opens into the lumen by a long duct which pierces the muscularis mucosae (Wilson and Washington, 1989). A sphincter is situated at the point where the oesophagus enters the stomach to prevent gastro-oesophageal reflux, i.e. to prevent acidic gastric contents from reaching stratified epithelia of the oesophagus, where they can cause inflammation and irritation (Wilson and Washington, 1989; Brown et al., 1993).
Comment:[homology-note] "The few structural specializations in (adult lampreys) pharynx include complex valves on the external gill openings that direct the tidal flow, and the division of the ancestral pharynx into an oesophagus and a respiratory pharynx.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000450", ontology="VHOG", source="DOI:10.1111/j.1096-3642.1996.tb01658.x Mallatt J, Ventilation and the origin of jawed vertebrates: a new mouth.
