The digestion of food in humans takes place in the gastrointestinal tract â a series of hollow organs (mouth, esophagus, stomach, large and small intestines) connected to form a long tube of about 24 feet in length which extends from the mouth to the anus.
Definition: Commercially prepared food designed for ease of consumption. Products designated as convenience or ready-to-eat foods are often prepared food that can be sold as hot, ready-to-eat dishes; as room-temperature, shelf-stable products; or as refrigerated or frozen products that require minimal preparation (typically just heating).
The Meal, Ready-to-Eat â commonly known as the MRE â is a self-contained, individual field ration in lightweight packaging bought by the United States military for its service members for use in combat or other field conditions where organized food facilities are not available.
