What are bile ducts?
The bile duct is a thin tube that extends from the liver to the small intestine. Its purpose is to transport bile. Bile is a fluid that breaks down fats during digestion. The liver secretes bile that is then stored by the gallbladder. The liver and gallbladder are connected to each other and to the small intestine. During meals, the gallbladder releases bile through the bile duct to help with the digestion of food in the intestines. Two areas of the bile duct system are involved in this process.
