The gallbladder has a capacity of about 50 millilitres (1.8 imperial fluid ounces). [2] The gallbladder is shaped like a pear, with its tip opening into the cystic duct. [4] The gallbladder is divided into three sections: the fundus, body, and neck. The fundus is the rounded base, angled so that it faces the abdominal wall.
Gallbladder and biliary-related diseases occurred in about 104 million people (1.6% of people) in 2013 and resulted in 106,000 deaths. [8] [9] Gallstones are more common among women than men and occur more commonly after the age of 40. [2] Gallstones occur more frequently among certain ethnic groups than others. [2]
Gallstones can form within the gallbladder and get stuck within the biliary tract, leading to various diseases depending on the location of the stone. [11] Gallstone disease, or cholelithiasis, is very common in the United States, impacting over 20 million people. [11]

[26] It is a small organ where the bile produced by the liver is stored, before being released into the small intestine.
Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
