Rationale 1: The URT consists of the nose, nasal cavity, pharynx, and paranasal sinuses. These passageways warm, humidify, and clean the air before it enters the lungs. The URT traps and removes particulate matter and many pathogens before they reach the lower portions of the lungs, where they would be able to access the capillaries of the systemic circulation.
Rationale 2:The lungs and associated structures is incorrect because the upper respiratory tract consists of the nose, nasal cavity, pharynx, and paranasal sinuses.
Rationale 3: The upper respiratory tract consists of the nose, nasal cavity, pharynx, and paranasal sinuses.
Rationale 4:The nose, nasal cavity, pharynx, and the lungs is incorrect. The upper respiratory tract consists of the nose, nasal cavity, pharynx, and paranasal sinuses.
