Explanation:

The anatomical division of the pharynx, located behind the mouth, of the soft palate above the level of the hyoid bone below, is called the oropharynx.

The oropharynx is the part of the throat just behind the mouth. It includes the base of the tongue, the soft palate, the tonsils, and the lateral and posterior throat. The functions of the oropharynx consist in helping the person to breathe, talk, eat, chew and swallow. Salivary glands in the oral cavity and oropharynx produce saliva, which keeps the mouth moist and aids in food digestion.
