The oral cavity includes the lips, the front two-thirds of the tongue, and the hard palate, or roof of the mouth. The oropharynx begins where the oral cavity stops. It includes the soft palate at the back of the mouth, the tonsils, the base of the tongue, and the part of the throat behind the mouth. The illustration also shows the throat, including the esophagus and the windpipe, or trachea, and nasal cavity, the air-filled cavity behind the nose.
