Jejunum. From Applegate, 2000.

je·ju·num

(jĕ-jū'nŭm), [TA]
The proximal (lateral) two fifths of the 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 circular folds (plicae circulares), being more vascular (redder in appearance), with the jejunal arteries forming fewer tiers of arterial arcades and longer vasa recta.
[L. jejunus, empty]

jejunum

(jə-jo͞o′nəm)
n. pl. jeju·na (-nə)
The section of the small intestine between the duodenum and the ileum.

jejunum

[jijo̅o̅′nəm] pl. jejuna
Etymology: L, jejunus, empty
the intermediate or middle of the three portions of the small intestine, connecting proximally with the duodenum and distally with the ileum. The jejunum has a slightly larger diameter, a deeper color, and a thicker wall than the ileum and contains heavy, circular folds that are absent in the lower part of the ileum. The jejunum also has larger villi than the ileum. Compare ileum. jejunal, adj.

jejunum

The length of small intestine lying between the DUODENUM and the ILEUM and occupying the central part of the ABDOMEN. Much of the enzymatic digestion of food, and most of the absorption, takes place in the jejunum. Absorption occurs through the thin walls of millions of tiny finger-like processes on the lining, called villi.

a part of the SMALL INTESTINE between duodenum and ileum.

Jejunum

The middle portion of the small intestine. It is approximately 8 ft (2.5 m) long and extends from the jejunum to the ileum.
