Right hepatic artery gives rise to which artery to supply the gallbladder?

• A. Cystic Artery
• B. Right Hepatic Artery Proper
• C. Left Hepatic Artery
• D. Gastroduodenal Artery

Answer: (A)

The gallbladder is supplied by the cystic artery, which most often branches from the right hepatic artery as it courses within Calot’s triangle to reach the gallbladder. This cystic artery is the vessel that actually delivers blood to the gallbladder walls, so identifying it as the artery that the right hepatic artery gives rise to explains why it is the correct choice. The other vessels listed are involved with other organs (left hepatic artery supplies the left lobe; gastroduodenal artery supplies stomach/duodenum; right hepatic artery (proper) is a main hepatic branch, but the vessel that specifically feeds the gallbladder is the cystic artery).
