Biliary system that transport bile (a substance that helps in digestion) from liver to intestine. It has two components , one is intrahepatic ( inside the liver)and another one is extra hepatic( outside the liver).It stores bile temporarily to gall bladder during its transport to duodenum. It is related to vital structures like portal vein, hepatic artery ,pancreas & duodenum .
Anatomy and functions of the biliary system :
The biliary system consists of the organs and ducts (bile ducts, gallbladder, and associated structures) that are involved in the production and transportation of bile. The transportation of bile follows this sequence:
1. When the liver cells secrete bile, it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts.
2. These ducts ultimately drain into the common hepatic duct.
3. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct, which runs from the liver to the duodenum (the first section of the small intestine).
4. However, not all bile runs directly into the duodenum. About 50 percent of the bile produced by the liver is first stored in the gallbladder, a pear-shaped organ located directly below the liver.
5. Then, when food is eaten, the gallbladder contracts and releases stored bile into the duodenum to help break down the fats.
