Summary
| Description | This presentation details what makes swallowing healthy or unhealthy. Specific attention is paid to the movement of food from the mouth to the esophagus. The act of swallowing typically takes less than one second, but the presenter divides the process into separate steps and evaluates each one, following a column of barium as it shows up on x-rays and passes through the mouth, oropharynx, hypopharynx, and esophagus. Various drawings of the larynx and esophagus are also used to illustrate this process. Credits: David J. Curtis. |
