What is the correct order of major branches of the abdominal aorta?

The correct order of the major branches of the abdominal aorta is indeed celiac trunk, SMA (superior mesenteric artery), and IMA (inferior mesenteric artery). Understanding the anatomy of these vessels is crucial in both clinical and surgical settings, as they supply various abdominal organs.

Beginning from the celiac trunk, which arises from the abdominal aorta around the level of the T12-L1 vertebrae, it branches into three major arteries: the left gastric artery, splenic artery, and common hepatic artery, supplying the foregut.

The superior mesenteric artery follows, branching off the abdominal aorta slightly below the celiac trunk, around the L1-L2 vertebral levels. The SMA supplies blood to a significant portion of the midgut, including the small intestine and parts of the large intestine.

Lastly, the inferior mesenteric artery branches off at a lower level, typically around L3, and supplies blood to the hindgut, including parts of the colon and rectum.

This anatomical sequence is essential for understanding blood supply to the gastrointestinal tract, as well as for diagnosing and treating conditions that may affect these arteries. Knowing the proper order helps in identifying possible sites of ischemia or planning surgical interventions
