In anoxia of liver, necrosis is seen in -a) Centrilobularb) Around the peripheryc) Around the central veind) Around the bile duct

**Core Concept**
Liver anoxia, also known as ischemic liver injury, occurs when the liver's blood supply is compromised, leading to cellular damage and necrosis. The liver's unique anatomy and blood flow patterns play a crucial role in determining the location and severity of tissue damage.

**Why the Correct Answer is Right**
In liver anoxia, the centrilobular region (Zone 3) is most susceptible to damage. This area receives blood from the terminal branches of the hepatic artery and portal vein, which are more prone to ischemia due to their high metabolic rate. The hepatocytes in this region are more densely packed and have a higher oxygen demand, making them more vulnerable to anoxia-induced injury. The centrilobular necrosis is often referred to as "ischemic hepatitis" or "shock liver."

**Why Each Wrong Option is Incorrect**
**Option A:** Centrilobular necrosis is the correct answer, so we'll explain the other options.
* **Option B:** Around the periphery, the liver's blood supply is more stable, and the hepatocytes are less densely packed, making this area less susceptible to anoxia-induced damage.
* **Option C:** Around the central vein is incorrect because the centrilobular region is actually located around the central vein, not the central vein itself.
* **Option D:** Around the bile duct is incorrect because bile ducts are not directly involved in the liver's blood supply and are not typically affected by anoxia-induced damage.

**Clinical Pearl / High-Yield Fact**
In cases of liver anoxia, the centrilobular necrosis is often accompanied by a characteristic histopathological finding: the presence of Councilman bodies, which are small, rounded hepatocytes with pyknotic nuclei and eosinophilic cytoplasm.

**Correct Answer:** A. Centrilobular
