**Core Concept**
The liver is divided into eight segments, also known as Couinaud liver segments, which are further divided into functional units based on their blood supply and drainage. Understanding the hepatic ducts' drainage pattern is crucial for liver surgery and interventional radiology procedures.
**Why the Correct Answer is Right**
The right hepatic duct typically drains segments V, VI, VII, and VIII, which are located in the right liver lobe. The right hepatic duct originates from the confluence of the right anterior and right posterior hepatic ducts, which drain the right liver lobe segments. This anatomical arrangement is essential for surgeons and radiologists to understand when performing liver resections or stenting procedures.
