A cross-section of the trachea reveals that C-shaped cartilage rings are present. What is the function of these rings? These rings are used to prevent food in the esophagus from blocking the airway during swallowing. These rings keep the respiratory passage open. These rings close the airway when a person is finished exhaling to prevent pathogens from invading the area. These rings diffuse oxygen and carbon dioxide into the bloodstream.
