1 Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. 2  Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.
The liver, the pancreas, and the sphincter of Oddi all play important roles. The liver provides a chemical called bile to the digestive process, and the pancreas provides pancreatic juice. These important chemicals flow into the small intestine to help with digestion. The flow of these chemicals is controlled by a muscle called the sphincter of Oddi. A sphincter is a muscle (usually round) that can open and close. When it's working properly, the sphincter of Oddi opens to allow bile and pancreatic juice to flow through, and then closes again. However, in a condition called sphincter of Oddi dysfunction, the sphincter muscle does not open when it should.
