Across
- 1. a organ that produces t cells and located superficial to the heart
- 5. Located between the lungs is responsible for pumping blood
- 8. stabilize the thoracic cage located between ribs
- 11. space between the visceral and parietal pleurae surrounding the lungs reduce friction during respiration
- 12. rests on the diaphragm and expands during respiration
- 15. conduit for air entering and leaving the lungs located in front of the esophagus
- 17. oxygenate blood and remove carbon dioxide located in the bottom of the left lung
- 18. transports food and liquids from the pharynx to the stomach located behind the trachea
- 20. responsible for air circulation and gas exchange in the upper lung areas
Down
- 2. enhances lung elasticity between superior and muiddle lung
- 3. oxygenating blood and removing carbon dioxide located in the middle of the right lung
- 4. passages that transport air into the alveoli located in lungs
- 6. Made of ribs and muscles, it protects thoracic organs
- 7. responsible for gas exchange located in the top of the left lung
- 9. contracting and flattening during inhalation to expand the lungs located below the lungs
- 10. allowing independent movement of lobes located between lower and middle lung
- 13. responsible for gas exchange located in the top of the right lobe
- 14. air sacs in the lungs that serve as the primary site for gas exchange
- 16. clusters of tiny air sacs at the end of the bronchioles in the lungs, serving as the primary site for gas exchange
- 19. shield for the heart located superior to the heart
