Final answer:
The celiac trunk consists of the left gastric artery, splenic artery, and common hepatic artery, which is a branch of the abdominal aorta located below the diaphragm; the common hepatic artery further divides and supplies blood to the liver, stomach, and gall bladder.
Step-by-step explanation:
The three vessels that form the celiac trunk are the left gastric artery, the splenic artery, and the common hepatic artery. The celiac trunk is a major branch of the abdominal aorta and is located within the abdomen just below the diaphragm where it branches from the abdominal aorta. The common hepatic artery further divides to form the hepatic artery properly supplying blood to the liver, the right gastric artery to the stomach, and the cystic artery to the gall bladder.
