superior mesenteric artery

Abbreviation: SMA
The second unpaired midline artery branching from the abdominal aorta; it originates 1 to 2 cm distal to the celiac artery. It supplies blood to the midgut, i.e., the distal half of the duodenum, the jejunum, the ileum, the ascending colon, and the proximal half of the transverse colon. Its branches include the inferior pancreaticoduodenal, jejunal, ileal, ileocolic, marginal, and right and middle colic arteries.
