Jejunum
In
anatomy of the
digestive system, the
jejunum is the central of the three divisions of the
small intestine and lies between the
duodenum and the
ileum. In adult
humans it is usually between 2-8m long.
The inner surface of the jejunum, its mucous membrane, is covered in projections called villi, which increase the area of tissue available to absorb nutrients from the gut contents.
