The gallbladder function
The gallbladder is about 10 cm long and contains about 50 ml of bile. Its coloration is green and it is composed of a muscular pouch which the wall is thin. It is covered outside by the peritoneum, called visceral peritoneum, which is a fine (serous) membrane that lines the abdominal cavity and the outside of the viscera contained by this cavity. It consists of two sheets: the visceral slip (which adheres to the bodies) and the parietal slip (which is against the wall of the abdominal cavity). Between these two sheets, there is a qualified virtual space for mobility on the other.
Gall bladder serves as reservoir for bile that is secreted (made) by the liver. Apart from its function of setting aside of bile, the gallbladder also plays a role at the time of the passage of the food bowl in the duodenum. In fact, at that time, its contraction will allow the evacuation of bile in the intestine, the role of bile is to allow the absorption of food and particularly fat.
Bile is stored in the gallbladder is not immediately required for digestion. Thus, in some cases, bile is not freed by the gallbladder 10 times more concentrated than that which enters the gall. The gallbladder is housed in a shallow dimple below the liver. Its end has a round shape and is slightly above the lower edge of the liver (underside). The contraction of the muscles in the wall of the gallbladder allows the flow of bile through the cystic duct and the common bile duct (called simply bile) corresponding to the meeting of the liver channel.
Regulation of the arrival of bile in the small intestine
Bile does not flow continuously in the small intestine (or in the duodenum) specifically. A sphincter (circular muscle arranged around the bile duct) regulates the output of bile in the direction of the duodenum as well as the release of pancreatic juice which also empties into the bile from the pancreas via the main pancreatic duct.
The liver produces bile continuously. When this sphincter is hermetically sealed, the bile produced in the liver will ebb in the cystic duct in the direction of the gallbladder and fill. It is then stored until it becomes necessary to the intestine to break, fragment large molecules.
Mechanism of formation of gallstones
The body contains cholesterol. The main route of excretion of this cholesterol is bile. Bile salts (bile components) keep cholesterol in solution in the bile. When cholesterol is in too high quantities or when bile salts are enough, cholesterol crystallises, creating the gallstones. The diagnosis of gallstones is relatively easy through the use of techniques based on Ultrasound (ultrasound).
Calculations prevent bile to be evacuated by the gall bladder to the point where it collapses. The pain felt by the patient are caused by the sharp crystals by the gallbladder. These pains usually radiate to the right chest area (right shoulder). The appropriate treatment in this case is a drug that dissolves the crystals. One can also try to reduce powder by use of ultrasound using a technique called lithotripsy. In some patients, the use of laser radiation or surgical removal of the gallbladder (cholecystectomy) are required.
The absence of gallbladder interferes with the normal functioning of the body. Indeed, the common bile duct will gradually expand and thus replace the role of the gall-bladder tank.
The presence of gallstones in the gallbladder leads to the occurrence of jaundice (jaundice). Indeed, the obstruction of the common bile duct prevents salts, and bile pigments in the intestine. This consequence is accumulation of these components in the blood and therefore called obstruction jaundice jaundice.
