Left colic artery
There are many veins and arteries that carry blood to and from the colon. There is an ascending colon, a descending colon, and a transverse colon. The descending colon is supplied with blood by the left colic artery, which is a branch of the inferior mesenteric artery. There are many parts of the body that get blood from this artery including the hindgut and part of the transverse and sigmoid colon. These are on the left side of the abdomen. This artery travels to the left side of the abdomen and branches off to supply blood to most of the left side of the colon. It also feeds into and supplies some blood to the marginal artery. The only part of the colon this artery does not supply blood to is the ascending colon on the right side of the abdomen. The left colic artery supplies blood to many parts of the colon, including the descending colon, the transverse colon and the sigmoid colon. It feeds into other larger arteries and supplies much of the blood to the left side of the colon.
