Swallowing Disorders: Introduction Swallowing is a complex function that affects the physical and mental health of all human beings. Not only does eating provide nutrients, but it also serves as important role in social interaction. The mechanism of Swallowing is a coordinated operation of the mouth, pharynx, and esophagus. Human beings swallow 600 times per day. Under normal circumstances, Swallowing is performed without thought or effort. Only the oral phase requires conscious effort. Once the bolus passes into the pharynx, involuntary reflexes serve to successfully pass it to the stomach.
