This pear-shaped sac primarily functions as a reservoir for bile that was synthesized at the level of the hepatocytes. While ingesting a meal, the presence of fats and proteins in the intestines stimulate the release of cholecystokinin; which acts at the level of the body and neck of the gallbladder, and cystic and extrahepatic ducts

The biliary tract collects, stores, concentrates, and delivers bile secreted by the liver. Its motility is controlled by neurohormonal mechanisms with the vagus and splanchnic nerves and the hormone cholecystokinin playing key roles. These neurohormonal mechanisms integrate the motility of the gallbladder and sphincter of Oddi (SO) with the gastrointestinal tract in the fasting and digestive.
