E

Explanation: 

Detailed explanation-1: -The middle part of the small intestine. It is between the duodenum (first part of the small intestine) and the ileum (last part of the small intestine). The jejunum helps to further digest food coming from the stomach.

Detailed explanation-2: -The jejunum is roughly 2.5 meters in length, contains plicae circulares (muscular flaps), and villi to absorb the products of digestion. The ileum is the final portion of the small intestine, measuring around 3 meters, and ends at the cecum.

Detailed explanation-3: -A long tube-like organ that connects the stomach and the large intestine. It is about 20 feet long and folds many times to fit inside the abdomen. The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach.

Detailed explanation-4: -Ileum. The ileum constitutes about three fifths of the distal small intestine and the jejunum makes the proximal two fifths. No clear demarcation is noted between the ileum and jejunum; however, there are some features which distinguish the ileum from the jejunum.
