(Help to Metabolism of Food)

System Description :

Having to do with the liver plus the gallbladder, bile ducts, or bile. For example, MRI (magnetic resonance imaging) can be applied to the hepatobiliary system. Hepatobiliary makes sense since "hepato-" refers to the liver and "-biliary" refers to the gallbladder, bile ducts, or bile.

Functions of the biliary system :

> The biliary system's main function includes the following :

To drain waste products from the liver into the duodenum.

To help in digestion with the controlled release of bile.

> Bile is the greenish-yellow fluid (consisting of waste products, cholesterol, and bile salts) that is secreted by the liver cells to perform 2 primary functions :

To carry away waste.

To break down fats during digestion.

Bile salt is the actual component that helps break down and absorb fats. Bile, which is excreted from the body in the form of feces, is what gives feces its dark brown color.

Parts of the Hepatobiliary System :

The biliary tract, (biliary tree or biliary system) refers to the liver, gall bladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin.
