Approximately how long is the alimentary canal during life, before smooth muscle tone is lost after death?

1. The alimentary canal, also called the gastrointestinal (GI) tract or gut, is a one-way tube from mouth to anus. 2. During life, with normal smooth muscle tone, it measures about 7.62 meters (25 feet) in length. 3. After death, once smooth muscle tone is lost, it stretches to closer to 10.67 meters (35 feet). 4. 2 meters, 15 meters, and 1 meter do not match the living-length figure of a typical adult's alimentary canal. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 23 "The Digestive System", section 23.1, p. 1087_
