mesenteric artery

The mesenteric artery is a vital blood vessel that supplies blood to the small intestine and parts of the large intestine. It originates from the abdominal aorta, which is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body.123

The mesenteric artery is part of the complex network of arteries that nourish the digestive system. Specifically, the superior mesenteric artery branches off the abdominal aorta and then further divides to supply blood to the small intestine and a portion of the large intestine. The blood from these organs is then collected by the superior mesenteric vein, which contributes to the portal vein that leads to the liver. This ensures that the digestive organs receive the oxygen and nutrients they need to function properly.12
