Where is the marginal artery?
The marginal artery of the colon, or artery of Drummond, is an artery that runs along the inside border of the large intestine, ending at the rectum.
What makes up the marginal artery?
The marginal artery of Drummond is formed by the anastomotic branches of the ileocolic, right colic, and middle colic artery, that arise from the superior mesenteric artery; and branches of the left colic and sigmoid arteries, which arise from the inferior mesenteric artery.
Why is the marginal artery important?
The marginal artery is an important connection between the SMA and IMA providing collateral flow in the event of occlusion or significant stenosis.
What artery supplies the colon?
The superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA) provide blood supply to the colon. Communication between these two vessels happens via the marginal artery, which runs parallel to the length of the entire colon.

Right marginal artery (Arteria marginalis dextra) The right marginal artery is a branch of the right coronary artery. It supplies the majority of the myocardium of the right ventricle of the heart. Some authors refer to this artery as the acute marginal artery, or the right marginal branch of right coronary artery.
What does the marginal artery connect?
Structure. The marginal artery runs in the mesentery close to the large intestine as part of the vascular arcade that connects the superior mesenteric artery and the inferior mesenteric artery. It provides an effective anastomosis between these two arteries for the large intestine.
Why is it called the marginal artery?

What does the marginal artery of Drummond supply?
The marginal artery, also known as the artery of Drummond, supplies the proximal descending colon at the splenic flexure. The artery of Drummond is an arterial arcade formed by an anastomosis between the distal branches of the superior and inferior mesenteric arteries.
What is the marginal artery of the colon (artery of Drummond)?
The marginal artery of the colon, or artery of Drummond, is an artery that runs along the inside border of the large intestine, ending at the rectum. This blood vessel connects the inferior mesenteric artery to the superior mesenteric artery and is formed from branches of the right colic, left colic, ileocolic, and middle colic arteries.
What passes through the marginal artery to the colon?
Straight vessels (known as vasa recta) pass from this marginal artery to the colon. The marginal artery is an important connection between the SMA and IMA providing collateral flow in the event of occlusion or significant stenosis. The junction of the SMA and IMA territories is at the splenic flexure.
What does the marginal artery connect to?
The marginal artery runs in the mesentery close to the large intestine as part of the vascular arcade that connects the superior mesenteric artery and the inferior mesenteric artery. It provides an effective anastomosis between these two arteries for the large intestine.
What is the number 9 artery in the colon?
Colonic blood supply (Marginal artery is #9) [edit on Wikidata] In human anatomy, the marginal artery of the colon, also known as the marginal artery of Drummond and artery of Drummond is an artery that connects the inferior mesenteric artery with the superior mesenteric artery.
