Across
  1. 4. PO2 influence mostly important in situations like __ or at high altitude
  2. 7. __ anhydrase is found at several locations, included the red blood cells (erythrocytes) and in the respiratory centers of the brain
  3. 11. The percent saturation is __ where the partial pressure of oxygen is high
  4. 13. Increased pulmonary ventilation in excess of metabolic requirements, resulting in decreased Pco2 and respiratory alkalosis
  5. 17. The __ effect reduced O2 in the tissues facilitates the loading of Hb with CO2 and H+ while increased O2 in the lungs promotes the dissociation of CO2 from Hb.
  6. 18. Encompasses two separate but related processes
  7. 21. __'s law states that at any constant temperature, the pressure exerted by a gas varies inversely with the volume of a gas
  8. 22. Underventilation in relation to metabolic requirements, resulting in increased Pco2 and respiratory acidosis
  9. 23. __ bodies are located in the carotid sinus
  10. 25. __ complex is a region rostral from the VRG where respiratory rhythm is generated
Down
  1. 1. __ Breuer reflex stretches receptors in the smooth muscle of the bronchioles inhibiting the medullary center to prevent over-inflation of the lungs
  2. 2. pressure Main factor determining the percent of hemoglobin saturation
  3. 3. __neurons; active in normal quiet breathing
  4. 5. the inward __ shift of Cl- in exchange to the efflux of HCO3- from red blood cells
  5. 6. Interior of plural sac:Pleural __
  6. 8. __ Chemoreceptors located in the medulla near the respiratory control center Provide excitatory input to inspiratory neurons
  7. 9. Inspiratory and __ neurons; activated upon demand
  8. 10. Thin-walled inflatable sacs
  9. 12. Most oxygen in the blood is transported bound to __ in erythrocytes
  10. 14. ventilation tidal volume x respiratory rate
  11. 15. __ Monoxide is a colorless, odorless gas that is the leading cause of death by poison worldwide
  12. 16. __bodies are located in the aortic arch
  13. 19. The __ effect increased CO2 and H+ at the tissues right-shifts the dissociation curve of O2
  14. 20. __ sac is a double-walled, closed sac that separates each lung from the thoracic wall
  15. 24. __ and carbon dioxide exchange across pulmonary and systemic capillaries caused by partial pressure gradients
