This model illustrates the anatomical structure of the liver, highlighting its vascular and ductal systems. The liver is divided into eight segments labeled I to VIII, which are grouped into four sections: Right Posterior Section (VI and VII), Right Anterior Section (V and VIII), Left Medial Section (I and IV), and Left Lateral Section (II and III). Key vascular structures include:

Right Hepatic Vein: Drains segments VI, VII, and VIII.
Middle Hepatic Vein: Drains segment IV.
Left Hepatic Vein: Drains segments II and III.

The model also shows the major ducts:

Hepatic Ducts: Merge to form the common hepatic duct.
Cystic Duct: Connects the gallbladder to the common bile duct.
Bile Duct: Formed by the union of the common hepatic duct and cystic duct, carrying bile to the duodenum.
Other structures include the Inferior Vena Cava, Portal Vein, and Hepatic Artery, which supply blood to and from the liver. The Gallbladder is depicted below the liver, connected by the cystic duct. The Umbilical Vein (remnant) is also labeled, indicating its location in the liver.
