Study Notes
Conducting Zone of the Respiratory System
- Comprised of structures including the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles.
- Functions to transport, warm, filter, and humidify air before it reaches the lungs.
Gas Exchange Location
- Gas exchange occurs in the alveoli, tiny air sacs in the lungs.
- Alveoli are surrounded by capillaries, allowing oxygen to enter the bloodstream and carbon dioxide to exit.
Surface Area and Smaller Airways
- The bronchioles, particularly the terminal and respiratory bronchioles, greatly increase surface area.
- These numerous smaller airways facilitate an efficient exchange of gases due to their extensive surface coverage.
Entry Point of Air
- Air enters the respiratory system through the nose or mouth.
- The nasal cavity filters and humidifies the incoming air, enhancing respiratory efficiency.
Lobes of the Right Lung
- The right lung is composed of three lobes: superior, middle, and inferior.
- These lobes allow for optimal organization and expansion during breathing.
