What is the primary function of the nasal conchae?

• A. Provide structural support
• B. Warm, humidify, and filter air
• C. Facilitate sound resonance
• D. Protect the nasal passages

Answer: (B)

The primary function of the nasal conchae is to warm, humidify, and filter air as it passes through the nasal cavity. The conchae, also known as turbinates, are bony structures covered with a mucous membrane that increase the surface area of the nasal cavity. This enhancement allows for more efficient interactions between the incoming air and the mucous membrane. The moist, warm surface of the conchae helps to raise the temperature of the air close to body temperature and adds moisture, which is crucial for maintaining healthy respiratory function. Additionally, the conchae trap dust, dirt, and other particulates, effectively filtering out harmful substances before the air reaches the lungs, thereby playing a critical role in respiratory health.
