Where the jejunum is, in 3D
The jejunum is the middle stretch of the small intestine, busy absorbing nutrients. It is part of the small intestine and belongs to the digestive system. It is roughly the first two-fifths of the small intestine after the duodenum and lies mostly in the upper left of the abdomen. Its wall is thicker than the ileum's, with more circular folds inside.
Frequently asked questions
Which body system does the jejunum belong to?
The jejunum belongs to the digestive system. The digestive system is made up of the digestive tract running from mouth to anus (oesophagus, stomach, small and large intestine) and the liver, gallbladder and pancreas, which make digestive juices and send them into the tract.
What else can you see alongside the jejunum?
The BAHI BODY 3D model of the small intestine also shows the duodenum and ileum.
Where is the small intestine?
The small intestine is the long tube between the stomach and the large intestine, running through the duodenum, jejunum and ileum.
Where does the jejunum end and the ileum begin?
There is no sharp border. The first two-fifths or so of the small intestine after the duodenum is called the jejunum and the remaining three-fifths the ileum.
