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.
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. Gallstones are generally small, hard deposits inside the gallbladder that are formed when stored bile crystallizes. A person with gallstones will rarely feel any symptoms until the gallstones reach a certain size, or if the gallstone obstructs the bile ducts.

The biliary system consists of the organs and ducts bile ducts, gallbladder, and associated structures that are involved in the production and transportation of bile. When the liver cells secrete bile, it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct.
Overview of the Liver and Gallbladder
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. It is not yet known how to compensate for the absence of liver function in the long term, although liver dialysis techniques can be used in the short term.
