The average length of the small intestine in an adult human male is 6.9 m (22 ft 8 in), and 7.1 m (23 ft 4 in) in an adult female. It can vary greatly, from as short as 4.6 m (15 ft) to as long as 9.8 m (32 ft). Recent studies indicate that small intestine may be shorter, around 3.5 m (11 ft 6 in), and that the length is less affected by age after childhood than expected. It is approximately 2.5â3 cm in diameter. The surface area of the human small intestinal mucosa averages 30 square meter. The small intestine is divided into three structural parts. The duodenum is a short structure (about 20â25 cm long) continuous with the stomach and shaped like a C.
The intestines are a long, continuous tube running from the stomach to the anus. Most absorption of nutrients and water happen in the intestines. The intestines include the small intestine, large intestine, and rectum. The small intestine (small bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum. The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter.
