By which movement does food move forward in the food pipe?
Answer and explanation
Correct answer: Wave-like muscular movement
Peristalsis is the governing concept in this question. It consists of rhythmic, wave-like contractions and relaxations of the muscles in the oesophageal wall. These contractions push the swallowed food toward the stomach, even when a person is not upright. Therefore option A is correct; blood flow, transpiration, and filtration are unrelated processes.
