The three parts of the small intestine are the duodenum, jejunum, and ileum. The duodenum is the first section where most digestion takes place, the jejunum is the middle section responsible for nutrient absorption, and the ileum is the final section that further absorbs nutrients and connects to the large intestine.
the duodenum (the first 25cm of the small intestine)
They are the duodenum, jejunum, and ileum.
They're much more numerous in the duodenum than in the ileum.
the duodenum comes first
Duodenum, Jejunum, Ileum
the jejunum is the middle portion of the small intestine
Distinguishing feature of the duodenum are the Brunner's glands, whereas the Peyer's patches make the ileum easily identificable. The common bile duct and the pancreatic duct enter the duodenum, whereas the ileum does not receive duct from other organs. Outermost layer of the duodenum is comprised of adventitia as it is located retroperitoneally, while the outermost layer of the ileum is represented by serosa(mesothelial cell are evident). The ileum has also more goblet cells than the duodenum. Duodenum represents major site of iron absorption, while the ileum-B12 absorption.
Alternative names will be, proximal small bowel (duodenum) and distal or terminal small bowel (ileum)
No, it is the duodenum.
The small intestine has three main divisions: - duodenum - jejunum, - ileum. Those are the main sections, but the duodenum could be divided further into: superior, descending, horizontal, and ascending portions.
