RESPIRATORY SYSTEM FUNCTION
Across
- 2. Balanced state of pressure during gas exchange in the lungs
- 3. The process by which gases move across the alveolar membrane in the lungs
- 5. Process which occurs when the gas pressure in the atmosphere exceeds that of the gas pressure in the lungs
- 6. Chest cavity containing lungs
- 7. Cellular organelles that consume oxygen for respiration
- 8. Descriptor for the condition of the respiratory surfaces that aids in gas exchange
- 12. Describes the increase in size of the lungs due to filling with air
- 13. Tiny hair-like structures in the respiratory system
- 14. Compound formed by the binding of oxygen to the red pigment found in erythrocytes
- 15. Percentage oxygen content (by volume) of atmosphere (6,3)
Down
- 1. Sticky substance that helps trap foreign particles in the respiratory system
- 2. Process which occurs during the relaxation of the diaphragm
- 4. Muscles between the ribs
- 9. The extent of respiratory membrane for efficient gas exchange (7,4)
- 10. Gases passively move 'down' their concentration ________?
- 11. Process which occurs during contraction of the external intercostals
