FAQs
What is the difference between upper and lower respiratory tract? The upper tract includes the nose, pharynx, and larynx, while the lower tract includes the trachea, bronchi, and lungs.
Why is the epiglottis important? It closes over the larynx during swallowing to prevent food from entering the airway.
How does the nasal cavity filter air? Hairs (vibrissae) trap large particles, and the mucous membrane captures smaller particles.
