Gallbladder and bile duct

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