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.
Foveolar cells line the surface of the stomach, the gastric pits, and the top part of gastric glands: the neck. They constitute a simple columnar epithelium, as they form a single layer of cells and are taller than their width.
