Biliary system
Biliary tract; Bile tract
The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.
The biliary organs and duct system that creates, transports, stores, and releases bile into the duodenum for digestion includes the liver, gallbladder, and bile ducts (named the cystic, hepatic, common, and pancreatic duct).

The biliary system includes:
- The gallbladder
