Small intestine: The part of the digestive tract that extends from the stomach to the large intestine.
The small intestine, or small bowel, lies between the stomach and the colon. The small intestine is about 6 m (20 ft) long. Its primary function is to digest and absorb nutrients. The small intestine makes up more than 70% of the length and 90% of the surface area ofthe gastrointestinal (GI) tract. The most common cancerous (malignant) tumors of the small bowel include adenocarcinoma, lymphoma, sarcoma, and carcinoids. In industrialized countries, adenocarcinomas occur most often.
