Question

Which of the following blood vessels supplies blood to the proximal large bowel?

1) Superior mesenteric artery
2) Inferior mesenteric artery
3) Hepatic artery
4) Splenic artery

Answer 1

The superior mesenteric artery, a branch of the abdominal aorta, supplies blood to the proximal large bowel, along with the small intestine and pancreas.

Step-by-step explanation:

The blood vessel that supplies blood to the proximal large bowel is the superior mesenteric artery. This artery is a branch of the abdominal aorta and is responsible for providing blood to the small intestine (duodenum, jejunum, and ileum), the pancreas, and most of the large intestine. The superior mesenteric artery, alongside the inferior mesenteric artery, plays a key role in the vascular supply to the intestines; the former generally services the proximal two-thirds and the latter the distal third of the large intestine.
