Figure 1. The liver is divided into four sections: the right posterior section, the right anterior section, the left medial section, and the left lateral section. Each section of the liver is further divided into segments: segments VI and VII make up the right posterior section, segments V and VIII make up the right anterior section, segment IV makes up the left medial section, and segments II and III make up the left lateral section. Segment I is found deep in the left side of the liver, in front of the inferior vena cava and behind the right, middle, and left hepatic veins.
