Overview
The throat (see the image below) is part of both the digestive and respiratory systems and is responsible for coordinating the functions of breathing and swallowing. From superior to inferior, the throat is subdivided into 3 sections: oropharynx, hypopharynx, and larynx. Together, the oropharynx, hypopharynx, and larynx function to sense and propel a food bolus from the mouth to the esophagus in a coordinated fashion while protecting the airway.
