where is the jejunum located in the human body
Jejunum The jejunum (/dʒɪˈdʒuːnəm/[2][3]) is the second part of the small intestine in humans and most higher vertebrates, including mammals, reptiles, and birds.
Small intestine Food from the stomach is allowed into the duodenum through the pylorus by a muscle called the pyloric sphincter.
Jejunum The jejunum lies between the duodenum and the ileum. The jejunum is considered to begin at the attachment of the suspensory muscle of the duodenum to the duodenum, a location called the duodenojejunal flexure.[4] The division between the jejunum and ileum is not anatomically distinct.[5] In adult humans, the small intestine is usually 6-7m long, about two-fifths of which (2.5 m) is the jejunum.[4]
Stomach In classical anatomy, the human stomach is divided into four sections, beginning at the gastric cardia,[6] each of which has different cells and functions.
