Which organ does the superior mesenteric artery primarily supply?

The superior mesenteric artery primarily supplies blood to the small intestine. It is a major artery that branches off from the abdominal aorta and delivers oxygenated blood to the majority of the small intestine, including the duodenum, jejunum, and ileum. This artery also provides branches that supply parts of the large intestine, but its primary role is in supplying the small intestine.

Understanding the vascular supply of the digestive organs is crucial for comprehending how nutrients are delivered and absorbed, as well as how various digestive disorders may affect blood flow. The structure and function of the superior mesenteric artery illustrate its importance in the overall gastrointestinal system.
