Detailed explanation-1: -Classification of the celiac trunk becomes easy if one considers the trunk to be composed of three main stems: the splenic, the hepatic and the left gastric artery, other vessels being less important collaterals.

Detailed explanation-2: -Answer and Explanation: The answer is c. the superior mesenteric artery. This artery does not branch off the celiac trunk however, the common hepatic artery, the left gastric artery, and the splenic artery all arise from the celiac trunk.

Detailed explanation-3: -The celiac artery supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen, and the superior half of both the duodenum and the pancreas. These structures correspond to the embryonic foregut.

Detailed explanation-4: -The right gastric artery arises from the proper hepatic artery. The left gastroepiploic artery is a branch of the splenic artery. The gastroduodenal artery gives off the right gastroepiploic artery. All of this makes up the vascular circle of the stomach.
