Q: What is the primary function of the nasal cavity in the respiratory system?
Solution:
The nasal cavity filters, warms, and humidifies the air before it enters the lungs.
Steps: 5
Show Steps
Step 1: Understand that the nasal cavity is a space inside your nose.
Step 2: Know that when you breathe in, air enters through the nostrils into the nasal cavity.
Step 3: Realize that the nasal cavity has tiny hairs and mucus that help filter out dust and germs from the air.
Step 4: Learn that the nasal cavity also warms the air to make it closer to body temperature.
Step 5: Remember that the nasal cavity adds moisture (humidity) to the air so it doesn't dry out your lungs.
