Gallbladder and bile duct
The gallbladder stores bile, a yellow-green fluid produced in the liver. Bile flows from your liver into your gallbladder, where it's held until needed during the digestion of food. When you eat, your gallbladder releases bile into the bile duct, where it's carried to the upper part of the small intestine, called the duodenum, to help break down fat in food.
