How do we swallow? — Expert Video

Dr. Rosemary Martino, professor and chair of the Department of Speech-Language Pathology at the University of Toronto, explains how swallowing works and why it is such a complex process. She describes how swallowing involves about 30 different muscles and multiple nerves working together under the control of the brain. Food is first chewed in the mouth, then moved by the tongue and throat muscles through the throat and into the esophagus, which carries it to the stomach. Dr. Martino explains that swallowing depends on precise coordination between the brain, nerves, and muscles, and that disruptions at any stage can lead to swallowing difficulties.
