The Function of the Gallbladder: Bile Production
After a meal, the gallbladder plays a crucial role in the digestive process by secreting bile. When food enters the small intestine, a hormone called cholecystokinin is released. This hormone triggers the contraction of the smooth muscles in the gallbladder, pushing bile through the cystic duct and into the common bile duct.
Simultaneously, the sphincter of Oddi, a muscular valve responsible for controlling the flow of digestive juices, relaxes. This relaxation allows bile to enter the small intestine. Once in the duodenum, the bile acids present in bile aid in the digestion and absorption of fats.
Gallstones: How They Form and Their Effects
Gallstones can develop in the gallbladder as pebble-like deposits. These growths, which are quite common, consist of either bilirubin or cholesterol, both of which are found in the sac-like organ. The symptoms experienced due to gallstones vary depending on their size and can include intense abdominal pain, jaundice, and fever. In cases of severe pain, surgical removal of the gallbladder may be necessary. However, without a gallbladder, bile will no longer be stored and instead directly flow from the liver to the small intestine through the hepatic and common bile ducts.
