Question

Movement of food from the mouth to the oesophagus is known as

• A. peristalsis
• B. deglutition
• C. segmentation
• D. None of the above

Answer 1

The correct option is B deglutition

Deglutition (swallowing) is the mechanism by which food is pushed from the oral cavity into the oesophagus and then pushed to the stomach. It helps transport bolus (masticated and lubricated food) or liquid from the mouth to the stomach.
Peristalsis is a series of wave-like muscle contractions that moves food to different parts of the digestive system.
Segmentation allows for greater mixing of food which results in the movement of food in both the directions i.e. front and back. Segmentation occurs mainly due to the rhythmic contractions in large and small intestine.
