File:Pharyngeal jaws of moray eels.svg

An illustration of the pharyngeal jaws of a moray eel, a "second set" of jaws contained within an animal's pharynx, distinct from the primary (oral) jaws. When the moray bites prey, it first bites normally with its oral jaws, capturing the prey. Immediately thereafter, the pharyngeal jaws are brought forward and bite down on the prey to grip it; they then retract, pulling the prey down the eel's esophagus, allowing it to be swallowed.

The pharynx is an organ found in animals. The pharynx is part of the digestive system and also the respiratory system.

It is part of the conducting zone of the respiratory system which is made up of the nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles; their function is to filter, warm, and moisten air and conduct it into the lungs.

"Pharynx" is pronounced /ˈfærɪŋks/[1][2]. It is from Ancient Greek: φάρυγξ . Its plural is "pharynges" (/fəˈrɪnz/), or "pharynxes" (/ˈfærɪŋksəz/). Its adjective form is "pharyngeal" (/ˌfærɪnˈəl/ or /fəˈrɪniəl/).
