Right hepatic duct drains all except
**Core Concept**
The right hepatic duct is one of the two main ducts that drain bile from the liver into the common bile duct. It is formed by the union of the right anterior and right posterior sectoral hepatic ducts, which in turn drain the right lobe of the liver.
**Why the Correct Answer is Right**
The right hepatic duct typically drains the right posterior sectoral hepatic duct, which includes the posterior segments of the right lobe (VII and VIII). It also drains the right anterior sectoral hepatic duct, which includes the anterior segments of the right lobe (V and VI). The right hepatic duct does not drain the left lobe of the liver, which is drained by the left hepatic duct. The left hepatic duct typically drains the left medial and left lateral sectoral hepatic ducts, which include the medial and lateral segments of the left lobe (III and II).
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the right hepatic duct does drain the right posterior sectoral hepatic duct, which includes the posterior segments of the right lobe (VII and VIII).
**Option B:** This option is incorrect because the right hepatic duct does drain the right anterior sectoral hepatic duct, which includes the anterior segments of the right lobe (V and VI).
**Option D:** This option is incorrect because the right hepatic duct typically drains the segments that are part of the right lobe, not the left lobe.
**Clinical Pearl / High-Yield Fact**
In the context of liver surgery or drainage procedures, it is essential to identify the correct anatomy of the hepatic ducts to avoid complications such as bile duct injury or leakage.
**Correct Answer: D.**
