The gallbladder is a small storage organ located inferior and posterior to the liver. Though small in size, the gallbladder plays an important role in our digestion of food. The gallbladder holds bile produced in the liver until it is needed for digesting fatty foods in the duodenum of the small intestine. Bile in the gallbladder may crystallize and form gallstones, which can become painful and potentially life threatening.

Clinical anatomy of liver and anamolies and it's diseases
The liver is an organ only found in vertebrates which detoxifies various metabolites , synthesizes proteins and produces biochemicals necessary for digestion and growth. Its other roles in metabolism include the regulation of glycogen storage , decomposition of red blood cells , and the production of hormones. The liver is an accessory digestive organ that produces bile , an alkaline fluid containing cholesterol and bile acids , which helps the breakdown of fat. The gallbladder , a small pouch that sits just under the liver, stores bile produced by the liver which is afterwards moved to the small intestine to complete digestion.
Overview of the Liver and Gallbladder
Located in the upper right portion of the abdomen, the liver and gallbladder are interconnected by ducts known as the biliary tract , which drains into the first segment of the small intestine the duodenum. Although the liver and gallbladder participate in some of the same functions, they are very different. Liver cells produce bile, which flows into small channels called bile canaliculi. These small channels drain into bile ducts. The ducts join to form larger and larger channels and eventually form the left and right hepatic ducts, which join to form the common hepatic duct.
The gallbladder is a pear-shaped organ that stores about 50 ml of the bile produced by the liver until the body needs it for digestion. It is about 7—10cm long in humans and is dark green in color. The gallbladder has a muscular wall that contracts in response to cholecystokinin, a peptide hormone that is synthesized by the small intestine. When food containing fat enters the digestive tract, the secretion of cholecystokinin CCK is stimulated, and the gallbladder releases the bile into the small intestine. The bile emulsifies fats and neutralizes acids in partly digested food. After being stored in the gallbladder, the bile becomes more concentrated to increase its potency and intensify its effect in fats.
The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract. When food enters the small intestine, a hormone called cholecystokinin is released, signaling the gallbladder to contract and secrete bile into the small intestine through the common bile duct. The bile helps the digestive process by breaking up fats. It also drains waste products from the liver into the duodenum, a part of the small intestine. An excess of cholesterol, bilirubin, or bile salts can cause gallstones to form.
