Study Notes

Upper Respiratory Tract

The upper airway structures consist of the nose, paranasal sinuses, pharynx, tonsils, adenoids, larynx, and trachea.

Lower Respiratory Tract

The lower respiratory tract consists of the lungs.
The lungs contain the bronchial and alveolar structures which are needed for gas exchange.
