The bile duct is a tube that transports bile from the liver to the small intestine. The gallbladder is attached to the bile duct by a small tube called the cystic duct. Bile is collected in the gallbladder between meals and empties into the bile duct through the cystic duct during a meal.
Bile is a digestive fluid made by the liver, stored in the gallbladder, and discharged into duodenum after food is ingested to aid in the digestion of fat. Normally, the pyloric sphincter prevents bile from entering the stomach.hile bile reflux involves fluid from the small intestine flowing into the stomach and esophagus, acid reflux is backflow of stomach acid into the esophagus. These conditions are often related, and differentiating between the two can be difficult.
