Across
  1. 5. a bone anchoring the ribcage and protecting the heart and lungs; located in the center of the chest.
  2. 8. a small section of the thoracic cavity located directly behind the sternum and in front of the pericardium; a protective space between the two.
  3. 9. a 10-inch muscular tube located behind the trachea, connecting the pharynx to the stomach to transport food.
  4. 12. primary conduit transporting deoxygenated blood from the heart's right ventricle to the lungs; located in the middle mediastinum of the chest.
  5. 13. conduit for all gases entering and leaving the body through breathing; located in the chest.
  6. 14. the main conduit for air leaving and entering the lungs; spans from the larynx to mid-chest.
  7. 15. primary muscle of respiration; located below the lungs.
  8. 16. functions as a center for blood distribution; located behind the left lung and sternum.
  9. 17. facilitates breathing by altering intrathoracic volume and pressure through muscle movement; protective, boundary of the thoracic cavity between the neck and the abdomen.
  10. 18. major blood vessel that carries deoxygenated blood from the heart to the left lung; originates from the right ventricle of the heart.
  11. 19. protects the heart, fixes it within the mediastinum, and prevents overfilling; surrounds the heart and the roots of the great vessels.
  12. 20. facilitates expansion of the lung lobes during respiration; spans horizontally across the right lung.
Down
  1. 1. a narrow, horizontal airway branching from the trachea at the carina to supply the left lung.
  2. 2. facilitates independent movement and uniform expansion during respiration; spans diagonally across the lower lung on both sides.
  3. 3. facilitates smooth lung movement by reducing friction, produces pleural fluid; outer serous membrane that lines the inner chest wall and diaphragm.
  4. 4. produces lubricating pleural fluid, reducing friction of the lung and the chest wall; a delicate membrane covering the lungs.
  5. 6. matures T-cells; located in the upper chest behind the breastbone.
  6. 7. stabilizes the chest wall and drives breathing by expanding or compressing the thoracic cavity; located between the ribs.
  7. 10. a friction-free space between the lungs and chest wall; enables frictionless breathing.
  8. 11. vital vessels carrying oxygenated blood from the left lung to the left atrium of the heart; located behind the aorta.
