Air breathed in through the mouth travels through the oropharynx, which also carries swallowed food, water, and salivary secretions through the food tube (esophagus) and then into the stomach.
When air is inhaled (inspired), it passes through the nose and the nasopharynx or through the mouth and the oropharynx.
The nasopharynx and oropharynx merge into the larynx, which is protected by a trap door called the epiglottis.
