Oesophagus. Light micrograph of a section through an whole oesophagus. The oesophagus passes food from the mouth to the stomach. The oesophagus lumen (white,centre) is lined by a layer of stratified squamous epithelium (green). 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 (yellow),the lamina propria,which is rich in elastin fibres. Outside of this is are layers of circular and longitudinal muscle (blue).
