6. The Viscera Pyloric Sphincter Muscle Pyloric Sphincter Muscle WHERE & WHY: The pyloric sphincter muscle has a dual function. WHERE & WHY: The pyloric sphincter muscle has a dual function. It holds food in the stomach during digestion by closing off the opening to the small intestine. It holds food in the stomach during digestion by closing off the opening to the small intestine. After digestion is completed the pyloric sphincter muscle contracts rhythmically to push the digested material (chyme) into the small intestine for further processing.

9. The Viscera Duodenum Duodenum WHERE: The anterior portion (about 3 cm) of the small intestine just behind the pyloric sphincter muscle. WHERE: The anterior portion (about 3 cm) of the small intestine just behind the pyloric sphincter muscle. WHY: Digestion is completed in the duodenum. Digestive juices from the liver and pancreas empty into the duodenum. WHY: Digestion is completed in the duodenum. Digestive juices from the liver and pancreas empty into the duodenum.

10. The Viscera Bile Duct Bile Duct WHERE: The bile duct runs in the mesentery between the liver and the duodenum. WHERE: The bile duct runs in the mesentery between the liver and the duodenum.
