The gross subdivisions of the stomach are the cardia, the fundus, the corpus (main body) and the pyloric region consisting of a pyloric antrum, a pyloric canal and the pylorus. Only three distinct histological regions are present since the microanatomy of the fundus and corpus is similar. In all regions of the stomach, the surface epithelium consists of tall, columnar mucus-secreting cells. The muscular coat consists of three layers of irregularly arranged smooth muscle.
== Small Intestine ==

The three subdivisions of the small intestine are the duodenum, the jejunum and the ileum. The general microscopic structure is similar in all three parts. In the 21 to 23 feet of small intestine, digestion of food materials continues after leaving the stomach, and its selective absorption occurs.
