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.
