Question

The rhythmic muscular contraction that pushes food from the oesophagus into the stomach is called _______.

• A. digestion

• D. mastication

Answer 1

The correct option is C peristalsis

Peristalsis is the rhythmic contraction of muscles in the oesophagus which pushes the food into the stomach. It is usually a unidirectional movement.

Digestion is the total process of break down of food into smaller particles that facilitate the absorption of nutrients.

Ingestion is the act of taking in food through the mouth.

Mastication is the process of chewing where the food is ground into smaller particles in the mouth with the help of teeth and tongue.
