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. 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. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct. This runs from the liver to the duodenum the first section of the small intestine. However, not all bile runs directly into the duodenum. This is a pear-shaped organ located directly below the liver. Then, when food is eaten, the gallbladder contracts and releases stored bile into the duodenum to help break down the fats.

Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder Figure 1. The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile. The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum. The liver is the largest gland in the body, weighing about three pounds in an adult.

Biliary System Anatomy and Functions

A bile duct is any of a number of long tube-like structures that carry bile , and is present in most vertebrates. Bile, required for the digestion of food, is secreted by the liver into passages that carry bile toward the hepatic duct , which joins with the cystic duct carrying bile to and from the gallbladder to form the common bile duct , which opens into the intestine., Get Instant Access. The small intestine receives not only chyme from the stomach but also secretions from the liver and pancreas, which enter the digestive tract near the junction of the stomach and small intestine.

Liver, Gallbladder, Bile Passages, Celiac Trunk and Portal Vein

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. Some components are synthesised by hepatocytes liver cells , the rest are extracted from the blood by the liver. Bile is secreted by the liver into small ducts that join to form the common hepatic duct. Between meals, secreted bile is stored in the gall bladder. During a meal, the bile is secreted into the duodenum to rid the body of waste stored in the bile as well as aid in the absorption of dietary fats and oils. The biliary tract refers to the path by which bile is secreted by the liver then transported to the duodenum , the first part of the small intestine.
