GENERAL HISTOLOGY

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 small intestine consists of three parts. The first part, called the duodenum, connects to the stomach. The middle part is the jejunum. The third part, called the ileum, attaches to the colon.

Detailed explanation-3: -Jejunum: The middle section of the small intestine carries food through rapidly, with wave-like muscle contractions, towards the ileum. Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Detailed explanation-4: -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.

Detailed explanation-5: -The jejunum has the typical histological pattern as the entire small intestine: mucosa, submucosa, muscularis and serosa. The mucosa is lined by simple columnar epithelium towards the lumen (lamina epithelialis). It contains enterocytes and goblet cells.
