what mechanism moves food through the gastrointestinal tract
The large, hollow organs of the digestive tract contain a layer of muscle that enables their walls to move. The movement of organ walls can propel food and liquid through the system and also can mix the contents within each organ. Food moves from one organ to the next through muscle action called peristalsis.rgans that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine-also called the colon-rectum, and anus. Inside these hollow organs is a lining called the mucosa.
