Content: Fig. 4: Image of the small and large intestine. Small Intestine Parts
There are three major small intestine parts, namely, duodenum, jejunum and ileum. Moving from the stomach to the large intestine, they appear in the following sequence: Duodenum ⇒ Jejunum ⇒ Ileum
These segments of the bowel also increase in length in the same sequence. It means duodenum is the smallest and the ileum the largest part. Overall length, however, may be greater in tall persons. It also increases when it is empty and after the individual dies. [ 6]
There is division of labor among different segments.
