Oesophagus lining. Coloured scanning electron micrograph (SEM) of the lining (epithelium) of the human oesophagus (gullet). As well as the larger folds seen here, the surface consists of small ridges (microplicae) that protect against abrasion by rough food. Mucus secretion also helps protect the lining. The oesophagus is a muscular tube, about 25 centimetres long, that runs from the back of the throat to the stomach.
