Stomach mucosa. Light micrograph (bottom left) and computer illustration (top right) of the lining of the stomach, known as the mucosa. The stomach is a muscular sac involved in storage and digestion of food. The surface of the mucosa consists of simple columnar cells (dark purple in micrograph) that secrete mucus. The mucus protects the stomach lining from digestive acids and enzymes that act on food in the stomach. Beneath the columnar cells are gastric pits, the glands that make the acids and enzymes needed to digest food. Stock Photo

These increase the surface area for the absorption of food. Within the columnar epithelium of the outer surface (pink) are goblet cells (stained blue with special staining), which secrete mucus to lubricate food and prevent self-digestion. The lamina propria (central core, ) contains the blood supply that transports the products of digestion. Magnification: x350 when printed at 10 centimetres wide. Stock Photo
