The structure of the esophagus fits its function in that

Question

Quizplus · Accepted Answer

The esophagus has smooth muscle that contracts in a coordinated fashion to move food from the mouth to the stomach through peristalsis, which is the rhythmic contraction and relaxation of muscles. Choice B is incorrect as the esophagus is not involved in directing food to the lungs. Choice C is also incorrect as the pharynx is responsible for initiating the swallowing reflex, but the esophagus is regulated by its own muscle contractions. Choice D is incorrect as the length of the esophagus does not determine the volume of food an animal can ingest.
