Peristalsis is a sequence of muscle contractions that transport food through the digestive tract in a wave-like pattern.
What is digestive system?
The human digestive system is made up of a collection of organs that work together to transform food into energy for the body.
The alimentary canal is a long tube that the food we eat passes through. It starts in the mouth (buccal or oral cavity), continues via the pharynx, esophagus or food pipe, stomach, small intestines, large intestines, rectum, and finishes in the anus.
As the food particles pass through the numerous compartments of the alimentary canal, they are gradually digested.
Thus, we can conclude that peristalsis is the movement of muscles through which food moves in the digestive system.
