Final answer:
Propulsion is the digestive system function that moves food from the mouth to the anus, involving peristalsis and contributing to overall digestion.
Step-by-step explanation:
Processes that afford movement of food from the mouth to the anus contribute to the digestive system function referred to as propulsion. Propulsion involves the movement of food along the alimentary canal and is an important process in the digestive system. It includes activities such as swallowing and the movement of food through peristalsis.
The six activities of the digestive process are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Propulsion specifically involves the movement of food through the alimentary canal using muscle contractions known as peristalsis and includes both voluntary and involuntary movements that help push food along the digestive tract from the moment food is swallowed until it is ejected as waste.
