Answer 1

Answer: (B)

1. Deglutition (swallowing) is the mechanism by which food is pushed from the oral cavity into the oesophagus and then pushed to the stomach.
2. It helps transport bolus (masticated and lubricated food) or liquid from the mouth to the stomach.
3. ​Peristalsis is a series of wave-like muscle contractions that moves food to different parts of the digestive system.
