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 (5 ft) long, which is about one-fifth of the whole length of the human gastrointestinal ...
The whole human GI tract is about nine meters (30 feet) long at autopsy. It is considerably shorter in the living body because the intestines, which are tubes of smooth muscle tissue , maintain constant muscle tone in a halfway-tense state but can relax in spots to allow for local distention and peristalsis .
The length of the small intestine can vary greatly, from as short as 3 metres (10 feet) to as long as 10.5 m (34 + 1 ⁄ 2 ft), also depending on the measuring technique used. [3] The typical length in a living person is 3–5 m (10– 16 + 1 ⁄ 2 ft). [4] [5] The length depends both on how tall the person is and how the length is measured. [3]
