Description
Oesophagus. Light micrograph of a section through an oesophagus from a pig. The oesophagus passes food from the mouth to the stomach. The oesophagus lumen (white) is lined by a layer of stratified squamous epithelium. This protects underlying tissue and enables the passage of solid material by the lubricant action of its glandular secretion. Surrounding this is a supporting layer of connective tissue, the lamina propria, which is rich in elastin fibres. Magnification: x5 when printed at 10 centimetres wide.
