Question

What changes take place as the air passes through the nasal cavity

Answer 1

Answer:

As air passes through the nasal cavities it is warmed and humidified, so that air that reaches the lungs is warmed and moist.The Nasal airways are lined with cilia and kept moist by mucous secretions. The combination of cilia and mucous helps to filter out solid particles from the air an Warm and moisten the air, which prevents damage to the delicate tissues that form the Respiratory System. The moisture in the nose helps to heat and humidify the air, increasing the amount of water vapour the air entering the lungs contains. This helps to keep the air entering the nose from drying out the lungs and other parts of our respiratory system. When air enters the respiratory system through the mouth, much less filtering is done. It is generally better to take in air through the nose.

It also does the following things:

1. Filters the air by the hairs and mucous in the nose

2. Moistens the air

3. Warms the air
