jejunum (je-ju´num) [NA]

The portion of small intestine, about 8 feet in length, between the duodenum and the ileum. The jejunum is distinct from the ileum in being more proximal, of larger diameter with a thicker wall, having larger, more highly developed plicae circulares, being more vasculer (redder in appearance) with the jejunal arteries forming fewer tiers of arterial arcades and longer vasa recti. [L. jejunus, empty]
