average length of the large intestine in cm
Large intestine In humans, the large intestine begins in the right iliac region of the pelvis, just at or below the waist, where it is joined to the end of the small intestine at the cecum, via the ileocecal valve. It then continues as the colon ascending the abdomen, across the width of the abdominal cavity as the transverse colon, and then descending to the rectum and its endpoint at the anal canal.[7] Overall, in humans, the large intestine is about 1.5 metres (5Â ft) long, which is about one-fifth of the whole length of the gastrointestinal tract.[8]
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.
