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 stored in gallbladder and when you eat food, gallbladder releases bile into the small intestine (duodenum). The tube that carries bile from gallbladder to the small intestine is called bile duct. Whenever there is blockage or obstruction in bile duct, it enlarges in it size or dilates. The first symptom you may notice is pale colored stool and dark urine if bile duct is blocked, if the blockage progresses further it causes yellow discoloration of your eyes and skin.
