Identification should include
- components of the upper respiratory tract (e.g., nostrils, nasal cavities, sinuses, pharynx, larynx, epiglottis, trachea) and their functions
- components of the lower respiratory tract (e.g., lungs, bronchi, alveoli, pleura, diaphragm) and their functions
- differentiation between inspiration and expiration.
Process/Skill Questions:
- What purpose do the sinuses serve?
- What can happen if food passes through the epiglottis into the windpipe and lungs?
- How does the diaphragm bring air into the lungs and then expel air from the lungs?
- What role does oxygen play in breathing?
- What role does carbon dioxide play in breathing?
