What is the wave-like movement that pushes food forward called?

Answer and explanation

Correct answer: Peristalsis

Peristalsis is the coordinated, wave-like contraction and relaxation of muscles in the wall of the alimentary canal. Behind the food bolus, muscles contract, while muscles ahead relax, producing forward movement through the oesophagus and intestine. Thus option A is correct. Transpiration is water loss from plants, respiration releases energy from food, and excretion removes metabolic wastes, so none of these describes food propulsion.
