Oesophagus lining. Coloured scanning electron micrograph (SEM) of the lining (epithelium) of the human oesophagus (gullet). The folded surface is covered by 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 | |
