is the part of the digestive system
of many animals
immediately behind the mouth
and in front of the esophagus
. In mammals
, it is where the digestive tract and the respiratory
tract cross, commonly called the "throat" (which term may also include the larynx
). The human
pharynx is bent at a sharper angle than other mammal pharynges, enabling us to produce a wider variety of sounds, but also putting us in danger of choking
The human pharynx is divided into three sections: the nasopharynx, lying behind the nasal cavity; the oropharynx, behind the oral cavity; and the laryngopharynx, posterior to the larynx.
