## **Core Concept**
The common hepatic artery is a vital branch of the celiac trunk that supplies oxygenated blood to the liver, pylorus, pancreas, and duodenum. Its ligation can have significant implications for the organs that depend on it for their blood supply.

## **Why the Correct Answer is Right**
The correct answer, , involves understanding the areas and organs supplied by the common hepatic artery and its branches. The common hepatic artery gives rise to the proper hepatic artery (supplying the liver) and the gastroduodenal artery (supplying the pylorus, pancreas, and duodenum). Ligation of the common hepatic artery would therefore impair blood supply to the liver (via the proper hepatic artery), the pylorus, and parts of the pancreas and duodenum (via the gastroduodenal artery).

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not accurately reflect an organ or area that would be primarily affected by the ligation of the common hepatic artery.
- **Option B:** This option is incorrect as it does not specify an organ directly impacted by the ligation of the common hepatic artery.
- **Option C:** This option is incorrect because, although the spleen receives blood from the celiac trunk, it is primarily supplied by the splenic artery, a separate branch of the celiac trunk, not directly by the common hepatic artery.
- **Option D:** This option is not provided for evaluation.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the liver has a dual blood supply from both the hepatic artery (about 25% of its blood supply) and the hepatic portal vein (about 75%). Therefore, ligation of the common hepatic artery may not immediately result in liver failure due to this dual supply, but it can still cause significant ischemia to the liver and other dependent organs.

## **Correct Answer:** . Liver, pylorus, pancreas, and duodenum.
