MASTICATION
Deglutition, or swallowing, occurs in the oropharynx and upper esophagus. The process begins voluntarily in the mouth and is then carried out involuntarily as the food or liquid passes through the pharynx and into the esophagus on its way to the stomach.
The tongue is the muscular organ responsible for initiating deglutition, or swallowing. It helps to move food towards the back of the mouth and into the pharynx, which then triggers the swallowing reflex.
Deglutition, or swallowing, consists of three stages: oral, pharyngeal, and esophageal. During the oral stage, the food is chewed and formed into a bolus before being voluntarily pushed to the back of the mouth. In the pharyngeal stage, the swallow reflex is triggered to move the bolus through the pharynx and into the esophagus. Finally, in the esophageal stage, peristalsis helps transport the food down the esophagus and into the stomach.
The larynx moves during the swallowing process, or deglutition, to protect the airway from food and liquid entering the lungs. This movement helps to close off the entrance to the trachea (windpipe) by raising the larynx and epiglottis, preventing aspiration of food or liquid into the respiratory system.
