Across
- 4. air from trachea to left lung
- 5. small balloon gas exchange with capillaries
- 6. conducts air to aveoli
- 7. separates right superior and middle lobes for lung expansion
- 9. transports food and liquids from throat to stomach
- 13. prevents lung friction
- 16. lobes control upper respiration
- 17. transports air from lungs, protection from invaders
- 19. connects pericardium membrane to the sternum
- 20. transports deoxygenated blood from the right ventricle to left lung
Down
- 1. control lower respiration
- 2. equalize lung pressure and prevent collapse
- 3. expands and contracts ribcage
- 8. transports oxygen from left lung to left heart atrium
- 10. separates lobes in both lungs for lung expansion
- 11. protects organs like heart and lungs
- 12. produces T-cells and secretes hormones
- 14. protects heart and reduces hearbeat friction
- 15. the diaphram aids this to create room for lung expansion
- 18. provides organ protection and rib support
