Swallowing, also known as deglutition, is a physiologic function involving coordinated muscle contractions that propel food and liquids from the oral cavity to the stomach. The process occurs in 3 distinct phases: oral, pharyngeal, and esophageal, with the oral phase being voluntary and the other 2 reflexive. The oral phase further subdivides into preparatory and propulsive stages. Each phase is defined by the location of the bolus during transit to the stomach. The oral and pharyngeal stages share anatomy with the respiratory tract, making airway protection during these stages essential. The anatomy and function of the structures involved in swallowing are discussed further in this activity.[1]
