The term "arteria mesenterica superior" refers to a major blood vessel in the human body that is part of the systemic circulation system. In English, it is commonly known as the "superior mesenteric artery."
The superior mesenteric artery arises from the abdominal aorta, which is the largest artery in the abdominal region. It typically originates slightly below the celiac artery, which supplies blood to the liver, stomach, and spleen. The superior mesenteric artery then extends downwards to supply blood to various regions of the intestine, including the jejunum and ileum, which are parts of the small intestine.
Often described as a comparatively thick-walled and medium-sized artery, the superior mesenteric artery has an essential role in the body's circulatory system. It carries oxygenated blood rich in nutrients from the aorta to the small intestine, providing necessary nourishment for the digestive process and sustaining the tissue cells in this region. Additionally, it also supplies blood to other structures in the abdomen, such as the pancreas and a portion of the large intestine (colon).
Any blockages, narrowing, or other issues in the superior mesenteric artery can lead to ischemia or insufficient blood supply, resulting in various complications like intestinal angina, bowel infarction, or even life-threatening conditions. Medical professionals often study and perform interventions, such as angioplasty or stent placement, in the context of superior mesenteric artery syndrome or other related disorders to ensure proper blood flow and prevent potential complications.
