the serosa
Muscular layer
The muscular layer, known as the muscularis externa, contracts to facilitate the movement of materials through the alimentary canal. This layer is made up of smooth muscle that helps propel food and waste products through the digestive system via peristalsis.
The distal end of the alimentary canal is the anus, where waste materials are expelled from the body.
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.
It moves ingested materials through the alimentary canal at a consistent rate preventing material from rotting.
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.
