The blood supply to the colon comes from the superior and inferior mesenteric arteries. Part of the rectum is supplied by the internal iliac system and this anastamoses with the lower branches of the inferior mesenteric system.
Its visceral branches provide blood to organs, while its parietal branches supply blood to the tissues of the abdominal body wall. The inferior phrenic artery is a parietal artery, the most superior branch of the abdominal aorta. It extends superiorly to provide blood to the diaphragm muscle at the top of the abdomen.
