Arteria Ileum is the medical term for the ileal artery, which supplies blood to the small intestine. There are several synonyms for this term, including the jejunal artery, ileojejunal artery, and mesenteric artery. The jejunal artery supplies blood to the jejunum, while the ileojejunal artery branches out to supply blood to both the ileum and jejunum. The mesenteric artery is a larger vessel that supplies blood to the small intestine as well as the large intestine and other abdominal organs. These synonyms are commonly used in medical literature and discussions involving the anatomy and function of the intestinal system.
