Question

Quizplus · Accepted Answer

The artery labeled 4 in the figure is located in the region of the large intestine, suggesting that it is part of the mesenteric circulation. The two mesenteric arteries are the superior mesenteric and the inferior mesenteric arteries. The superior mesenteric artery supplies blood to the small intestine, while the inferior mesenteric artery supplies blood to the large intestine. Therefore, the artery labeled 4 is most likely the inferior mesenteric artery. Option A is incorrect because the superior mesenteric artery arises from the abdominal aorta at a higher level than the inferior mesenteric artery. Option C is incorrect because the renal artery supplies blood to the kidneys, which are located higher up in the abdomen. Option D is incorrect because iliac arteries are located in the pelvic region, not the abdominal region.
