Solution

The correct option is C Alimentary canal
Peristalsis is the series of involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract. They occur as progressive wavelike contractions. Peristaltic waves occur in the alimentary canal. In the oesophagus, peristaltic waves begin at the upper portion of the tube and travel the whole length, pushing food ahead of the wave into the stomach.
