Deglutition
Correctly pair each basic function of the digestive system with the correct description.
Digestion-Breakdown of large organic molecules into their component parts -Mastication-Process by which teeth break food into smaller particles to increase the total surface area Ingestion- The intake of solid or liquid food into the stomach Propulsion-Movement of food from one end of the digestive tract to the other Absorption-Movement of molecules from the digestive tract into the circulation or lymphatic system
The vestibule of the oral cavity is the space between the teeth and
cheeks

connective
The elimination of semi-solid waste products from the body is called
defecation
