which of the following prevents food from entering the airway during swallowing?
Best Answer: Trachea is a common biological term for an airway through which respiratory air transport takes place in organisms. The cells that line the trachea have minuscule hairs, which collect any dust that you inhale, and prevent it from entering your lungs. It is then removed by coughing. To prevent food from entering your windpipe, it has a small flap of skin at the entrance (epiglottis). When you eat, this flap closes over your trachea to prevent food from entering.
