The small intestine connects the stomach to the large intestine. The first section of the small intestine is the duodenum. It is C-shaped and about 25 centimeters long. For the purposes of anatomic reference, the duodenum is divided into four parts. Bile and pancreatic juices are secreted in the duodenum to continue the digestive process.
