The pharynx, or throat, is the passageway leading from the mouth and nose to the esophagus and larynx. The pharynx permits the passage of swallowed solids and liquids into the esophagus, or gullet, and conducts air to and from the trachea, or windpipe, during respiration.

Digestion begins when food enters the mouth (oral cavity). Both mechanical and chemical digestion occur in the mouth. The esophagus acts as a connection between the mouth and the stomach, but no digestion occurs here. The bolus then reaches the stomach, where more mechanical and chemical digestion take place.

The pharynx is the part of the digestive tract that leads to the esophagus. The epiglottis is located within the pharynx. Its job is to close so that food doesn’t enter the trachea during the act of swallowing. 3. Esophagus The esophagus is just the connection between the pharynx and the stomach.
