Swallowing is a very complex act for the body, actually. It requires the normal function of the brain, several nerves and muscles, two muscular valves, and a swallowing tube of some sort.

The swallowing tract extends from the mouth to the stomach. The act of swallowing normally occurs in three phases. In the first phase, food or liquid is contained in the mouth by the tongue and palate. This phase is the only one we can control.

The second phase of swallowing begins when the brain makes the decision to swallow. At this point, a complex series of reflexes begin. The food is thrust from the oral cavity into the throat. At the same time, two other events occur: A muscular valve at the bottom of the throat opens, allowing food to enter the esophagus, and other muscles close the airway to prevent food from entering the airways. This second phase of swallowing takes less than half a second.

The third phase of swallowing begins when food enters the muscular tube known as, esophagus. The muscular tube that produces waves of coordinated contractions (peristalsis). As the esophagus contracts, a muscular valve at the end of the esophagus opens and food is propelled into the stomach. The third phase of swallowing takes six to eight (6-8) seconds to complete.
