Answer 2

Answer:

Mastication permits easier deglutition (swallowing) and faster chemical breakdown in the digestive tract. During mastication, salivary glands secrete saliva to soften the food into a bolus (semi-solid lump). ... From the esophagus, the bolus passes through a sphincter (muscular ring) into the stomach.
