Inferior Mesenteric Artery

The inferior mesenteric artery is an oxygen-rich blood vessel which comes off the anterior surface of the abdominal aorta at approximately 1.5 cm above the point where it forks into the common iliac arteries, at the level LIII. The inferior mesenteric supplies the transverse colon and the rectum. Along the way, the inferior mesenteric artery gives off the colic, sigmoid, and superior rectal branches.
