The gall bladder symptoms is about 10 cm long and contains about 50 ml of bile. Its color is green and is composed of a muscular bag whose wall is thin. It is covered externally by peritoneum, called the visceral peritoneum, which is a thin membrane (serosa) that lines the abdominal cavity and the outside of the viscera in this cavity. It consists of two layers: the visceral (which adheres to organs) and parietal (which is against the wall of the abdominal cavity). Between these two sheets, there is a called virtual space, allowing the mobility of one another.

The gall bladder symptoms serves as a reservoir for bile that is secreted (made) by the liver. Apart from its function of setting aside the bile, the gallbladder also plays a role during the passage of the bolus into the duodenum. Indeed, at that time, its contraction will allow the discharge of bile into the intestine, the role of bile is to enable food absorption and especially of fats.

The bile that is stored in the gall bladder symptoms is not immediately needed for digestion. Thus in some cases, the bile that is not released from the gallbladder is 10 times more concentrated than that which enters the gallbladder. The gallbladder is housed in a shallow pit located below the liver. Its end is rounded and slightly above the lower edge of the liver (bottom). Muscle contraction of the gallbladder wall allows the flow of bile through the cystic duct and the bile duct (called simply bile) corresponding to the meeting of the hepatic duct and cystic duconduit.

Regulating the arrival of bile into the small intestine
Bile does not flow continuously into the small intestine (or more accurately into the duodenum). A sphincter (circular muscle placed around the bile duct) regulates the release of bile toward the duodenum and the release of pancreatic juice, which also comes flowing into the bile duct from the pancreas through the main pancreatic duct .

The liver produces bile continuously. When this sphincter is tightly closed, bile produced in the liver will flow back into the cystic duct towards the gallbladder and fill. It is then stored until it becomes necessary for the intestine to break, break up large molecules.

The gallbladder contracts as a result of a product: cholecystokinin (CCK) which is a hormone made by the intestines. Cholecystokinin is released into the blood when a bolus acid containing fat enters the small intestine (specifically in the duodenum). CCK but not only has the function to stimulate contractions of the gallbladder, it also stimulates the secretion of pancreatic juice and other by an action on the sphincter muscle of the bulb which allows the bile and juices the pancreas enter the duodenum.
