The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.
For food to properly pass through the alimentary canal, digestion must first occur. The process of moving food through the alimentary canal is called propulsion.
The food goes right through the digestive system from one end to the other, and is egested in the faeces.
The muscular movement of the intestinal canal is called peristalsis.

mouth (oesophagus)
Food in its varying states of digestion is moved through the hollow alimentary canal by means of a series of muscular contractions known as peristalsis, which squeezes the alimentary canal, in much the way that you would squeeze a tube of toothpaste to move toothpaste through the tube.
A series of muscular contractions, which squeeze the alimentary canal, called peristalsis, are what moves food all the way through the alimentary canal, from beginning to end.
Alimentary canal.
The digestive tract is called alimentary canal because its parts form a long tube through which we absorb the nutrition in our food. The word "alimentary" comes from the Latin word for nourishment, alimentum.
