The stomach contractions, which move the chyme from near the periphery of the stomach toward the pyloric sphincter, are called

  • A. the pyloric pump.
  • B. peristaltic waves.
  • C. mixing waves.
  • D. mass movements.
Correct Answer: C

Rationale: The correct answer is C: mixing waves. Mixing waves are the stomach contractions that help mix the chyme near the periphery of the stomach and move it towards the pyloric sphincter for further digestion. Peristaltic waves (B) are rhythmic contractions that propel food through the digestive system, not specifically in the stomach. The pyloric pump (A) is not a recognized term in gastrointestinal physiology. Mass movements (D) refer to contractions in the large intestine that move feces towards the rectum, not in the stomach.
