3. How does the process of breathing work?

Breathing involves two main processes: inhalation, where air is drawn into the lungs, and exhalation, where air is expelled from the lungs.

4. What is the difference between the upper and lower respiratory tracts?

The upper respiratory tract includes structures like the nose and nasal cavity, while the lower respiratory tract includes the trachea, bronchi, and lungs.

5. What role do alveoli play in respiration?

Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

6. What is the diaphragm and its function?

8. What are common diseases of the respiratory system?

Common diseases of the respiratory system include asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer.

9. How does respiratory anatomy vary among different species?

Respiratory anatomy can vary significantly among species, with different adaptations for breathing depending on their environment, such as gills in fish and lungs in mammals.

10. What is the role of cilia in the respiratory system?

Cilia are tiny hair-like structures that line the respiratory tract and help to trap and expel particles and pathogens from the airways.
