Study Notes
Upper Respiratory Tract
- Components include the nose, nasal cavity, sinuses, and pharynx.
- Does NOT include the lungs and trachea; this is a common misconception.
- Main function is to warm, filter, and moisten the air inhaled before it enters the lower respiratory tract.
Lower Respiratory Tract
- Comprises the trachea, bronchi, bronchioles, and lungs.
- Function is primarily to facilitate the transport of gases (oxygen and carbon dioxide) to and from the bloodstream.
- Gas exchange occurs at the alveoli, tiny air sacs in the lungs where oxygen enters the blood and carbon dioxide is expelled.
True or False Statements
- True: The upper respiratory tract excludes the lungs and trachea.
- True: The upper respiratory tract is essential for warming, filtering, and moistening air.
- True: Gas exchange occurs in the alveoli within the lungs.
- True: The main function of the lower respiratory tract involves the transportation of gases.
