Right colic artery

The right colic artery is a blood vessel that supplies oxygenated blood to the ascending colon, which is part of the large intestine. It is one of the branches of the superior mesenteric artery, which is a major artery in the abdomen.

Anatomy

The right colic artery typically arises from the superior mesenteric artery, although its origin can sometimes vary. It travels to the right side of the abdomen, where it divides into ascending and descending branches. These branches supply blood to the ascending colon and the right part of the transverse colon.

Branches

• Ascending branch: This branch ascends to supply the upper part of the ascending colon and anastomoses with the middle colic artery.
• Descending branch: This branch descends to supply the lower part of the ascending colon and anastomoses with the ileocolic artery.

Function

The primary function of the right colic artery is to provide oxygenated blood to the ascending colon. This is crucial for the proper functioning of the colon, including the absorption of water and electrolytes from digested food.

Clinical Significance

The right colic artery can be involved in various medical conditions, such as ischemic colitis, where reduced blood flow to the colon can cause inflammation and injury. Surgical procedures involving the colon, such as a right hemicolectomy, often require careful consideration of the right colic artery to ensure adequate blood supply to the remaining parts of the colon.
