what is the length of human small intestine
Small intestine The length of the small intestine can vary greatly, from as short as 2.75 m (9.0 ft) to as long as 10.49 m (34.4 ft).[3] The typical length in a living person is 3m-5m.[4][5] The length depends both on how tall the person is and how the length is measured.[3] Taller people generally have a longer small intestine and measurements are generally longer after death and when the bowel is empty.[3]
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.
Swallowing 5) Closure of the nasopharynx
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]
