I WONDER - How Do Humans Breathe?

The video explains the respiratory system's key functions, focusing on the nose's role. Cilia in the nose trap pollen, dust, and germs to prevent them from reaching the lungs. Turbinates in the nose help catch germs and adjust the air temperature to ensure it is suitable for the lungs.

What is the primary function of the cilia in the nose?

• To trap pollen, dust, and germs

• To enhance the sense of smell

• To produce mucus

• To humidify the air

Which of the following is NOT a function of the cilia?

• Cooling the air

• Trapping pollen

• Catching dust

• Preventing germs from entering the lungs

How do turbinates contribute to respiratory health?

• By enhancing vocal resonance

• By trapping germs and regulating air temperature

• By producing antibodies

• By filtering blood

What happens to the air as it passes through the turbinates?

• It is filtered for oxygen

• It becomes more humid

• It is adjusted to the right temperature

• It is mixed with carbon dioxide

What is the role of the nose in the respiratory system?

• To expel carbon dioxide

• To store oxygen

• To filter and condition the air

• To produce sound
