B. To propel food through the esophagus
C. To break down carbohydrates
D. To aid in speech production

Answer 1

The function of the pharyngeal constrictors is to propel food through the esophagus.

Step-by-step explanation:

The function of the pharyngeal constrictors is to propel food through the esophagus.

During the process of swallowing, the soft palate rises to close off the nasopharynx, the larynx elevates, and the epiglottis folds over the glottis. The constrictor muscles of the pharynx then contract, forcing the food bolus into the esophagus and initiating peristalsis.

For example, when you eat a bite of food and swallow, the pharyngeal constrictors contract to push the food down from the pharynx to the esophagus, allowing it to move further into the digestive system.
