The small intestine is made up of the duodenum, jejunum, and ileum. Together with the esophagus, large intestine, and the stomach, it forms the gastrointestinal tract. In living humans, the small ...

This article, part 4 in a 6-part series, describes the physiology and functions of the jejunum and ileum, the last two sections of the small intestine, where most absorption of nutrients takes place ...

Sixty-five cases of benign and malignant primary tumors of the duodenum, jejunum and ileum are reviewed. In 33 the tumors were malignant: 18 were adenocarcinomas, 13 were lymphosarcomas and 2 were ...

The second domain, the jejunum, has a large surface area on highly specialized epithelial cells that facilitate efficient nutrient absorption. The ileum is the third domain responsible for ...

Ileum The ileum has a thinner wall with shorter villi and is less vascular and has more lymphoid tissue than the jejunum. The ileum also has a less porous epithelial layer, so it is less ...

The duodenum is about 25 cm (10 inches) long; the jejunum is about 2.5 m (8 feet) long and the ileum is about 3.6 m (12 feet) long. Anatomy of the small intestine ...

Both the jejunum and the ileum have linings with many folds that increase the surface area of the small intestine (about 2,700 square feet or 250 square meters) for maximized nutrient absorption.

The jejunum is the second part of the small intestine, between the duodenum and ileum sections. The main function of the jejunum is absorption of nutrients that have undergone enzymatic digestion ...

Small intestine Made up of three segments—the duodenum, jejunum, and ileum—the small intestine is the workhorse of digestion. This is where most nutrients are absorbed.

It has three sections: the duodenum, the jejunum, and the ileum. Around one-third of people with Crohn’s disease have inflammation only in their ileum.
