It contains cholesterol, bile salts, bilirubin, phospholipids, and other substances. From the liver, bile flows into the gallbladder. Here, water and electrolytes are removed to concentrate the bile, making the stored bile more potent.

When dietary fat enters the small intestine, it triggers the release of the hormone CCK. CCK then stimulates the gallbladder to contract, releasing concentrated bile into the cystic duct. The cystic duct joins up with the common bile duct, which enters the small intestine.

Then, the bile emulsifies fats, breaking large fat globules into smaller droplets. If the bile becomes saturated with .
