What is DUODENUM, What does DUODENUM mean, DUODENUM meaning, DUODENUM definition, DUODENUM explanation

The duodenum[help 1] is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine may be used instead of duodenum.[5] In mammals the duodenum may be the principal site for iron absorption.[6]

The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine.

In humans, the duodenum is a hollow jointed tube about 25–38 cm (10–15 inches) long connecting the stomach to the jejunum. It begins with the duodenal bulb and ends at the suspensory muscle of duodenum.[7] It can be divided into four parts.
