Across
- 2. the exchange of oxygen and carbon dioxide between the alveoli and bloodstream
- 4. reinforced by cartilage to make it stay open C-shaped so it doesn't block the esophagus
- 7. regulates airflow, allowing them to control the amount of air reaching the alveoli
- 9. oxygen-carrying blood
- 10. the movement of anything from high to low concentration
- 12. carbon dioxide-carrying blood
- 13. series of enzyme reactions that break down glucose to produce 2 ATP + 2 pyruvate
- 14. a muscle that helps you inhale and exhale
- 15. energy produced
- 17. where ATP is made
- 18. tiny air sacs at the end of the bronchioles
Down
- 1. it contracts to elevate ribs, example include diaphragm, which contracts to expand thoracic cavity
- 3. respiration that requires oxygen, produces a lot of ATP
- 5. process that recycles NAD+ so glycolysis can continue
- 6. the release of energy (ATP) from organic molecules
- 8. where glycolysis takes place
- 11. the exchange of air between the atmosphere and the lungs - achieved by the physical act of breathing
- 16. the movement where air moves from high pressure to low pressure, the ribcage is pulled inwards and downwards
