7. The Gallbladder Secretes Bile

Following a meal, the small intestine releases a hormone called cholecystokinin; this causes the smooth muscles in the gallbladder to contract. In doing so, it pushes bile through the cystic duct and into the common bile duct. At the same time, the sphincter of Oddi—a muscular valve that controls the flow of digestive juices—also relaxes, which allows bile to enter the small intestine. In the duodenum, bile acids facilitate the digestion and absorption of fats.
