What problem will occur in the oesophagus if peristalsis stops?

Answer and explanation

Correct answer: Food will not move properly to the stomach

The governing concept is peristalsis, the involuntary, wave-like contraction and relaxation of muscles in the alimentary canal. After swallowing, these waves push the food bolus through the oesophagus toward the stomach, even without gravity being the main force. If peristalsis stops, forward transport is impaired and food may remain stuck or move very slowly. Therefore A is correct; B, C, and D are biologically unrelated and impossible outcomes.
