Which single branch of the abdominal aorta supplies blood to the small intestine (duodenum, jejunum, and ileum), the pancreas, and a majority of the large intestine?
Explanation
This question assesses the ability to identify the major abdominal artery responsible for supplying the small intestine and most of the large intestine.
