swallowing biomechanics

Swallowing biomechanics involve a coordinated sequence of muscle movements that safely move food or liquid from the mouth to the stomach. It begins with the mastication (chewing) and preparation of the bolus (food or liquid), then the tongue pushes the bolus to the back of the mouth. During this process, the soft palate rises to close the nasal passage, and the voice box (larynx) moves upward to prevent entry into the airway. The throat muscles then contract to propel the bolus downward through the esophagus, a muscular tube that transports it to the stomach. This intricate process ensures efficient and safe swallowing.
