What part of the body does the pharynx connect to?

The pharynx is a muscular tube that plays a crucial role in both the respiratory and digestive systems. It acts as a passageway for food and air, connecting the mouth and nasal cavities to both the esophagus and the larynx. The connection to the esophagus is particularly important because it allows for the transport of ingested food and liquids from the throat to the stomach. When we swallow, the pharynx helps funnel the food bolus into the esophagus, which then directs it toward the stomach for digestion.

In contrast, the larynx and trachea are primarily involved in the respiratory system rather than digestion. The larynx is responsible for producing sound and protecting the airway during swallowing, and while the trachea serves as the main airway for air passage to and from the lungs, it doesn’t play a role in the process of swallowing or food transport. Thus, the pharynx's direct connection to the esophagus makes it clear why this option is the correct one.
