Your liver constantly makes digestive fluid called bile. Bile travels from your liver to your gallbladder, a small organ in your belly. Your gallbladder sends bile to your small intestine through a tube called the common bile duct. Bile helps your body digest fats. It’s made up of:
Bile salts (bile acids): Substances that help your body absorb fats and fat-soluble vitamins.
Bilirubin: A waste product that develops when red blood cells break down.
Cholesterol: A wax-like substance that helps break down any fatty foods you eat.
As you digest food, your gallbladder contracts. These contractions help push bile into the common bile duct.
