Pharynx
The
pharynx 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.
