Liver and Gallbladder

Description

Situated in the right upper quadrant, the liver is rendered semi-translucent to expose the intrahepatic biliary tree coursing through the hepatic parenchyma, from peripheral canaliculi and lobular units toward segmental ducts and the right and left hepatic ducts near the porta hepatis. A green gallbladder lies on the visceral (inferior) surface, with its fundus projecting inferior to the liver’s sharp anterior margin and its body tapering proximally toward the neck. Medially, the cystic duct joins the common hepatic duct to form the common bile duct, which descends toward the second part of the duodenum, while the surrounding upper torso provides positional context under the costal margin. Clean landmarks. Lateral orientation emphasizes relationships that matter in practice: the gallbladder fundus is the point most likely to be encountered on surface and intraoperative inspection, and its projection below the inferior hepatic border helps explain why a distended gallbladder can become palpable in obstructive jaundice (Courvoisier sign). The branching pattern of bile ducts within the liver clarifies where obstruction occurs in choledocholithiasis versus hilar cholangiocarcinoma, and why injury near the cystic duct and common hepatic duct junction remains a central hazard during cholecystectomy. Ductal anatomy is unforgiving. Suitable for hepatobiliary teaching in gross anatomy, abdominal ultrasound and CT correlation modules, and surgical education materials covering the Calot triangle region, biliary colic, acute cholecystitis, and bile leak patterns. It also fits textbook figures on hepatic lobules, bile formation, and extrahepatic duct confluence in an adult male torso context. Anatomical accuracy verified by SciePro's Medical Advisory Board.
