Across
  1. 1. : Ratio of carbon dioxide output to oxygen uptake at the lungs.
  2. 3. : Normal respiratory quotient value (0.8 on mixed diet).
  3. 5. : Abbreviation for respiratory exchange ratio.
  4. 6. : Diffusion of carbon dioxide from tissues into venous blood.
  5. 9. : Oxygen and carbon dioxide exchanged in the lungs and tissues.
  6. 11. : Ratio of CO2 produced to O2 consumed at tissue level.
  7. 13. : Process of gas diffusion at systemic capillaries and tissues.
  8. 17. : Law governing gas solubility in blood proportional to partial pressure.
  9. 18. : Movement of oxygen from alveoli into pulmonary capillary blood.
  10. 19. : Diffusion of oxygen from blood into tissues for cellular metabolism.
  11. 20. : Form of hemoglobin carrying carbon dioxide
Down
  1. 2. : Site of gas exchange in the lungs.
  2. 4. : Driving force for gas diffusion across membranes.
  3. 7. : Volume of gas diffused per minute per mmHg pressure difference.
  4. 8. : Thin barrier between alveolar air and blood for diffusion.
  5. 10. : Normal respiratory exchange ratio, approximately equal to RQ at rest.
  6. 12. : Abbreviation for respiratory quotient.
  7. 14. : Gas diffusing more rapidly than oxygen due to higher solubility.
  8. 15. : Principle stating diffusion is proportional to surface area and gradient, inversely to thickness.
  9. 16. : Formed when oxygen binds hemoglobin in blood.
