The large and small intestines of the average adult human, when stretched, are only an average of 25 feet long and cannot stretch around the world. It would take the intestines of multiple humans to stretch the circumference of Earth.
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).

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.
