Light micrograph of a section of the human gastric mucosa,the internal lining of the stomach,showing the gastric pits. The stomach mucosa synthesises and secretes digestive gastric juice,a watery mix of hydrochloric acid and the digestive enzyme pepsin. A thick coating of mucus prevents autodigestion. The gastric glands contain 3 main cell types: mucus secreting cells,covering the upper surface & lining the gastric pits; hydrochloric acid-secreting cells,located in the middle part of the gland; lastly,pepsin- secreting cells clustered at the base of the gland.
