Anatomical terminology |
In humans, the duodenum is a hollow jointed tube about 25–38 centimetres (10–15 inches) long connecting the stomach to the middle part of the small intestine.[4][5] It begins with the duodenal bulb and ends at the suspensory muscle of duodenum.[6] Duodenum can be divided into four parts: the first (superior), the second (descending), the third (transverse) and the fourth (ascending) parts.[5]
