In a gross anatomy and physiology lab, an instructor wants to highlight blood flow to the intestinal tract. Into which artery do they need to pump colored ink to demonstrate blood flow to this area?

C)Lumbar artery
D)Middle sacral artery

Question

Quizplus · Accepted Answer

The superior mesenteric artery is responsible for supplying blood to the small intestine, cecum, ascending and transverse colon, and part of the duodenum. Pumping colored ink into this artery would demonstrate blood flow to the intestinal tract. The phrenic arteries supply blood to the diaphragm, the lumbar artery supplies blood to the muscles and spinal cord in the lumbar region, and the middle sacral artery supplies blood to the sacrum and coccyx. None of these arteries would provide a demonstration of blood flow to the intestinal tract.
