I WONDER - How Do Humans Breathe? Me Pregunto - Cómo Respiran Los Humanos?

The video tutorial explains the respiratory system's key functions, focusing on the nose's role in filtering air. It describes how nasal hairs, called cilia, trap pollen, dust, and germs to prevent them from reaching the lungs. Additionally, the video covers the function of turbinates, which help catch germs and regulate the temperature of inhaled air to ensure it is suitable for the lungs.

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

• To humidify the air

• To produce mucus

• To trap pollen, dust, and germs

• To enhance the sense of smell

How do turbinates contribute to respiratory health?

• By trapping germs and regulating air temperature

• By filtering blood

• By increasing oxygen absorption

• By producing antibodies

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

• It is filtered for oxygen

• It is heated or cooled

• It is humidified

• It is mixed with carbon dioxide

Why is it important for the air to have the perfect temperature when reaching the lungs?

• To maintain body temperature

• To avoid dehydration

• To ensure optimal oxygen absorption

• To prevent lung infections

Which structures in the nose are responsible for trapping germs?

• Cilia and turbinates

• Nasal septum

• Olfactory bulbs

• Sinuses
