Explanation:

• Absorption is the process of nutrients being taken into the bloodstream, not mechanical breakup in the mouth.
• Mastication is the act of chewing, which mechanically breaks up food particles in the mouth.
• Salivation is the production of saliva, which has a role in moistening food but not mechanical breakup.
• Peristalsis is the wave - like muscle contractions in the digestive tract (e.g., esophagus, intestines) for moving food along, not in the mouth for mechanical breakup.

mastication
