It is a paired artery, with one for each of the testes. It is the male equivalent of the ovarian artery. Because the testis is found in a different location than that of its female equivalent, it has a different course than the ovarian artery. They are two slender vessels of considerable length, and arise from the front of the aorta a little below the renal arteries. Each passes
Celiac artery cannot be safely ligated in a living person, and obstruction of the celiac artery will lead to necrosis of the structures it supplies. The celiac artery is the only major artery that nourishes the abdominal digestive organs that does "not" have a similarly named vein. Most blood returning from the digestive organs (including from the area of distribution of the celiac artery) is diverted to the liver via the portal venous system for further processing and detoxification in the liver before returning to the systemic circulation via the hepatic veins.
