3. A, I: Sinuses Cavities that are filled with mucous.
Moisten the air and surrounding tissue

4. B. Nasal Cavity Cilia: filters the incoming air Add to your diagram

5. T. Epiglottis
Cartilaginous flap that prevents food from going into the lungs

6. J, K, L. Pharynx Contracts to move food to the esophagus

7. N. Esophagus
Muscular tube that automatically pushes food downward to the stomach

8. M. Larynx and Vocal Cords
Vibrate and enable you to talk

9. O.) Trachea Provides air to the lungs
Contains cartilage to keep the pipe open
Secretes mucous: provides moisture and kills bacteria

10. D. Bronchus Branch off of the trachea; take air to the lungs

11. G. Terminal Bronchioles
Branch off of the bronchus
Contain alveoli for gas exchange

12. E. Alveoli: Gas exchange:
Oxygen goes from the alveoli to the capillaries
CO2 goes from the capillaries into the alveoli
Alveoli Expanding:
Alveoli and Capillaries:

13. F.) Capillaries
Warms air
Gas Exchange

14. R. Parietal Pleura
Fluid filled, lines the thoracic cavity (rib cage)

15. Q. Visceral Pleura
Fluid filled, lines the lungs, decrease friction as lungs expand
