Which artery supplies the ileum, cecum, and appendix?

The ileum, cecum, and appendix receive their blood supply primarily from the ileocecal artery. This artery is a branch of the superior mesenteric artery, which plays a broader role in supplying the small intestine and part of the large intestine. The ileocecal artery specifically branches out to provide blood to the cecum and the appendix, which are situated near the junction of the small intestine and the large intestine, known as the ileocecal junction.

The anatomy of this area is crucial for many interventional radiological procedures, as any issues such as appendicitis or ileocecal lesions can have a significant impact on vascular supply and subsequent treatment planning. Understanding the vascular anatomy helps in both diagnostic imaging and therapeutic interventions.

While the superior mesenteric artery indeed supplies the entire region, it is the ileocecal artery that specifically targets the ileum, cecum, and appendix directly, making it the most precise answer for this question.
