The gallbladder (sometimes gall bladder) is a small non-vital organ that aids in the digestive process and stores bile produced in the liver.
The gallbladder is a hollow organ that sits in a concavity of the liver known as the gallbladder fossa. In adults, the gallbladder measures approximately 8 cm in length and 4 cm in diameter when fully distended. It is divided into three sections: fundus, body, and neck.
The function of the gallbladder is to store bile and concentrate. Bile is a digestive liquid continually secreted by the liver. The bile emulsifies fats and neutralizes acids in partly digested food.
After being stored in the gallbladder, the bile becomes more concentrated than when it left the liver, increasing its potency and intensifying its effect on fats. Most digestion occurs in the duodenum.
Gallbladder disease includes inflammation, infection, stones, or blockage (obstruction) of the gallbladder.
The gallbladder is a sac located under the liver. It stores and concentrates bile produced in the liver. Bile aids in the digestion of fat, and is released from the gallbladder into the upper small intestine (duodenum) in response to food (especially fats).
