1) The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus. An adult’s digestive tract is about 30 feet (about 9 meters) long.
2) In humans, the small intestine is about 6 meters or 20 feet long and the large intestine is about 1.5 meters or 5 feet long. The gastrointestinal tracts of the Chimpanzee, Orangutan, and adult human and a human fetus were studied and compared by Stevens and Hume in 1995.
