After working through this study unit you will be able to:
- Name the parts of the gallbladder and the biliary system.
- Describe their function and neurovasculature.
- Understand the relations of the gallbladder to the nearby structures.
The gallbladder is a small intraperitoneal organ, located below the liver, to which it is functionally connected through the extrahepatic duct system. While the liver produces bile, the gallbladder’s main function is to store the bile that it receives from the liver and concentrate it by removing water and electrolytes.
The following video will help you learn everything you should know about the gallbladder, its anatomy, function, relations to surrounding structures and clinical importance.
