Right hepatic vein drains which segment of the liver-
**Core Concept**
The liver is divided into segments based on its blood supply and drainage. The **right hepatic vein** is one of the three main hepatic veins responsible for draining the liver. Understanding the segmental anatomy of the liver is crucial for surgical and radiological interventions.
**Why the Correct Answer is Right**
The right hepatic vein specifically drains the **right posterior inferior segment (VI)** and **right anterior inferior segment (V)**, but most notably, it is associated with the drainage of segments **V, VI, and VII**. This is because the right hepatic vein is located in the right hepatic fissure and receives blood from these segments.
**Why Each Wrong Option is Incorrect**
**Option A:** This is incorrect because the left hepatic vein primarily drains the left lateral segment (II and III).
**Option B:** This option is incorrect as it refers to a different segmental drainage pattern.
**Option D:** This is not accurate as the middle hepatic vein drains segments IV, V, and VIII.
**Clinical Pearl / High-Yield Fact**
Remembering that the liver is divided into segments based on the hepatic veins' drainage is key. The right hepatic vein's drainage of segments V, VI, and VII is a critical point for surgical planning, especially in liver resections.
**Correct Answer:** C. segments V, VI, and VII
