Food is moved through the pharynx and then enters the esophagus. This is the muscular tube that connects the throat to the stomach. Your esophagus is about 10 inches long, and it acts only as a passageway for food and drink. The esophagus passes behind the airway to the lungs and in front of the spinal column. It pierces the diaphragm before reaching the stomach. Food moves through your esophagus by a wavelike series of muscular contractions called peristalsis.
The tonsils and adenoids are housed with the pharynx. After food is chewed, the tongue pushes it to the back of the throat to be swallowed. The pharynx pushes food into the stomach, where it passes into the small and then the large intestine. View slideshow of images above.
