]. The duodenum is the first and the shortest segment of small intestine. It receives partially digested foods from stomach and pancreatic secretions containing digestive enzymes; it plays important roles in digesting foods. The jejunum lies in the midsection of intestine, connecting the duodenum and ileum. It contains circular folds and villi to increase surface area for absorbing small nutrient particles that were enzymatically digested in the duodenum. The absorbed nutrients then enter liver through the enterohepatic circulation. The ileum is the third part of small intestine and contains villi similar to those in jejunum.
