Formation and Orientation The small intestine is on average about five feet long. It is composed of four distinct structural parts; the cecum, colon, and anus.

Formation and Orientation The small intestine is on average between 22 feet 6 inches and 24 feet 4 inches. It is composed of three distinct structural parts; the duodenum, the jejunum, and the ileum. The duodenum is the part of the intestine where most chemical breakdown happens; it is also the shortest part of the intestine. It starts at the duodenal bulb and stops...
The stomach is the hollow organ that helps along digestion after mastication (chewing). It is the next step after the esophagus and before the small intestines. Formation and Orientation The stomach is composed of four parts. The cardia is the first part of the stomach in the digestive tract.
