Arteriae jejunales

from Wikipedia, the free encyclopedia
Branches of the inferior mesenteric artery

The arteriae jejunales (Latin for 'empty bowel arteries '') are arteries in the abdominal cavity that supply the bowel . There are about 15 arteries, the first two to three of which arise from the first part of the superior intestinal artery ( Arteria mesenterica superior ), the rest from the second part of this vessel. The arteriae jejunales run in the mesentery to the small intestine and form multi-row arcade-like anastomoses among themselves . These vascular arcades ensure the continuous blood supply to the jejunum during the intestinal peristalsis . The actual intestinal inflows are functional end arteries and arise from the convex part of these vascular arcades.
