Across
- 1. respiratory tract, airway from the nose through the larynx (the resp. organs in the head/neck)
- 3. system, a system of plasma proteins involved in defense against pathogens
- 5. escalator, mechanism of debris removal
- 10. lung capacity, max amount of air the lungs can contain
- 12. increase in local blood flow rapidly delivers leukocytes
- 15. capacity, amount of air that can be inhaled and then exhaled with max effort; the deepest breath.
- 16. immediate and intense type I reaction
- 18. space between the posterior margin of soft palate and epiglottis
- 22. volume, amnt of air left in the lungs after max expiration and can never be voluntarily exhaled.
- 25. attraction to chemicals that guide them to the site of injury or infection
- 31. lymph vessels, flow into lymph nodes
- 32. reserve volume, the amnt of air in excess of tidal volume that can be inhaled w/ max effort.
- 33. deletion, the removal through apoptosis of B and T cells that have expressed self receptors
- 35. pleura, adheres to the mediastinum/inner surface of the rib cage/sup. surface of the diaphragm
- 36. immunity, employs antibodies;don't directly destroy pathogens but tag them for destruction
- 37. T cells that passed the test demonstrating their ability to respond to antigens
- 38. reserve volume, amount of air in excess of tidal volume that can be exhaled with max effort.
- 39. maneuver, taking a deep breath/holding it by closing the glottis/then contracting the abdomen
- 40. vessels, travel alongside veins and arteries and empty into lymph nodes
Down
- 2. presence of air in the pleural cavity
- 4. bacteria/viruses/other pathogens are digested by neutrophils/macrophages
- 6. the rupture/destruction of cell by agents: complement proteins and hypotonic solutions
- 7. state of permanently inactive T cells (that are self reactive)
- 8. capacity, max amount of air that can be inhaled after a normal tidal expiration
- 9. lymph vessels, flow out of lymph nodes
- 11. fever-reducing
- 13. the collapse of part or all of a lung
- 14. selection, elimination or conversion of self-reactive T cells
- 17. lymph node diseases
- 19. volume, the air inhaled and exhaled in one cycle during quiet breathing.
- 20. residual capacity, amount of air remaining in the lungs after a normal tidal expiration
- 21. ducts, the largest of the lymphatic vessels
- 23. poster. to larynx, from the superior epiglottis to the inferior margin on cricoid cartilage
- 24. continuations of the airway that lack supportive cartilage
- 26. clearance, clearing foreign antigens from bloodstream
- 27. respiratory tract, regions from trachea through the lungs (the respiratory organs of the thorax)
- 28. immunity, employs lymphocytes that directly attack, destroy foreign cells or diseased host cells
- 29. slit in mediastinal surface through which the lung receives the root of the lung
- 30. pleura, lines the thoracic wall and forms the surface of the lung
- 34. presenting cells, trigger cellular response by exposing antigens in a form recognizable by T cells
