Content: This is not considered a true sphincter because it does at times allow stomach contents to enter the esophagus. Some mammals, like rodents, have a true gastroesophageal sphincter and can not regurgitate (this is why poisoning is an effective measure in killing mice and rats). Stomach
The stomach is a J-shaped pouch that empties its content into the small intestine. It can be divided into three regions: the fundus, body, and pylorus. A pyloric sphincter prohibits backflow from the small intestine into the stomach. The functions of the stomach are to store food as it is mechanically churned with gastric secretions, initiate digestion of proteins, carry on limited absorption, and move food (a pasty material called chyme) into the small intestine. Small Intestine
The small intestine is about 1 inch wide and about 12 feet long (in a cadaver, it will measure about twice this length because the muscle wall is relaxed). It is divided into three regions: the duodenum, jejunum, and ileum.
