Respiration is inhibited for the 1 to 3 seconds required for food to clear the pharynx during each swallowing.

Question

Quizplus · Accepted Answer

During swallowing, the epiglottis closes over the trachea to prevent food or liquid from entering the lungs. This inhibits breathing (respiration) for about 1 to 3 seconds, allowing the food to pass through the pharynx and into the esophagus on its way to the stomach. Once the food has cleared the pharynx, the epiglottis opens and normal breathing resumes.
