Understanding the Gallbladder, Biliary Ducts, and Liver Functions

This chapter explores the anatomy and functions of the liver, gallbladder, and biliary ducts. The liver is the largest organ in the body and is responsible for manufacturing bile, which is stored in the gallbladder. The gallbladder has a pear-shaped structure with three parts and plays a crucial role in bile storage and release. Biliary ducts transport bile from the liver to the gallbladder and then to the intestine. This chapter also covers imaging techniques such as ERCP, T-Tube, and operative cholangiograms, essential for assessing these organs.
