Which of the following is NOT a main artery of the body?

The hepatic artery is not considered one of the main arteries of the body when compared to the other options provided. The main arteries are typically those that serve as major conduits for blood distribution from the heart to various parts of the body.

The ascending aorta, for instance, is the primary artery that carries blood directly out of the heart, making it a central part of the circulatory system. The external carotid artery is crucial as it supplies blood to the face and neck, while the common iliac arteries are key vessels that supply blood to the lower extremities and pelvis.

In contrast, the hepatic artery primarily supplies blood to the liver and, while important, is categorized more as a regional artery rather than a main arterial vessel of the systemic circulation. Thus, the hepatic artery does not hold the same position in arterial hierarchy as the other options listed.
