Frequently Asked Questions

1 Make a list of all the parts of the body that air flows through on its way to the lungs

The respiratory system includes the nose, mouth, throat, voice box, windpipe, lungs, and diaphragm.

2 Why is it better to breathe through your nose than through your mouth?

Nose breathing is more beneficial than mouth breathing. Breathing through your nose can help filter out dust and allergens, boost your oxygen uptake, and humidify the air you breathe in. Mouth breathing, on the other hand, can dry out your mouth.

3 What are alveoli?

Alveoli are tiny air sacs present within the lungs which appear as a bunch of grapes. They mainly promote the exchange of gases.

4 What is the role of cilia in our respiratory system?

Tiny hair called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
