What are the wave-like contractions of the esophagus that help move food down the esophagus called?

• A. Ingestion
• B. Regurgitation
• C. Digestion
• D. Peristalsis

Answer: (D)

Peristalsis is the wave-like contraction of the esophageal muscles that pushes swallowed food down to the stomach. When you swallow, the circular muscles behind the bolus contract to squeeze it forward while the muscles in front relax, creating a coordinated wave that travels down the esophagus. This rhythmic action moves contents through tubular organs and is distinct from ingestion (taking in food), regurgitation (backward movement of contents), or digestion (the breakdown of food).
