The bottom part of the stomach is called the pyloric area. At the bottom of the stomach is another opening. This leads to the small intestine. One of the most important parts of the stomach (and generally of the digestive system) is the bacterial fauna that populates it.
The mucosa of stomach is divided in three layers. The surface epithelium : surface epithelium contains gastric pits and gastric glands. Gastric pits are invagination of epithelium into lamina propria (second layer of mucosa). Gastric glands produce enzymes, HCl (hydrochloric acid) and gastric hormones.
