4. It is the source of oxygen (air for terrestrial animals, water for aquatic animals). Q: What is the respiratory medium? S2C06 Jeopardy Review Image modified from: Pearson Education Inc; publishing as Pearson Prenctice Hall © 2006

5. Q: What is a higher oxygen concentration/being easier to pump? This is an advantage of air being the respiratory medium as opposed to water. S2C06 Jeopardy Review

6. A: What is keeping respiratory cells moist? This is an advantage to water being the respiratory medium instead of air. S2C06 Jeopardy Review

7. A: What is gas exchange? The uptake of O and the discharge of CO. S2C06 Jeopardy Review

8. A: Thin, moist, large surface area Characteristics that maximize gas exchange across respiratory surfaces? S2C06 Jeopardy Review

9. A: What are gills? S2C06 Jeopardy Review Outfoldings of the body surface that are suspended in water; used by many aquatic animals for gas exchange

10. A: What are lungs? Respiratory organs used by terrestrial animals; all respiration occurs in one place S2C06 Jeopardy Review

11. A: The gases diffuse across the membrane of every cell in the body. The simplest animals (sponges, cnidarians, and flatworms) respirate this way. S2C06 Jeopardy Review

12. A: What is tracheal system/trachea? Branched air tubes that extend to every section in the body, used by insects for respiration S2C06 Jeopardy Review

13. A: What is they respirate across their entire outer skin? Process by which earthworms and amphibians respirate S2C06 Jeopardy Review

14. A: Breathing…seriously. S2C06 Jeopardy Review What is the inhalation and exhalation of air?

15. A: What is positive pressure? The type of pressure by which amphibians respirate that involves drawing air into the oral cavity, then forcing it down the trachea. S2C06 Jeopardy Review

16. A: What is negative pressure? The type of pressure by which mammals respirate…PULLING air into the lungs. S2C06 Jeopardy Review

17. A: What is the medulla (oblongata)? The part of the brain that sets breathing rhythms based on the pH in the brain fluid S2C06 Jeopardy Review

18. A: What are air sacs? (posterior and anterior) The adaptation that allows birds to renew air in lungs and have higher oxygen concentrations S2C06 Jeopardy Review

19. A: What are pulmonary veins? S2C06 Jeopardy Review Type of blood vessels that circulate gas from the high pressure lungs to the heart

20. A: What are arteries? S2C06 Jeopardy Review Type of blood vessels that circulate gases from heart to low pressure tissue cells

21. A: What are hemoglobin and hemocyanin? The most abundant oxygen transporting respiratory pigments S2C06 Jeopardy Review

22. A: What is partial pressure? The proportion of atmospheric pressure contributed by a single gas. S2C06 Jeopardy Review

23. A: The drop in pH caused by presence of CO2. The reason more carbon dioxide causes hemoglobin to release the oxygen bound to it. S2C06 Jeopardy Review

24. A: What is oxygen? Extremely active mammals consume large amounts of this gas. S2C06 Jeopardy Review Image from: http://io.uwinnipeg.ca/~simmons/16cm05/1116/16anim3.htm

25. A: What is carbon dioxide? Gas besides oxygen that hemoglobin transports. S2C06 Jeopardy Review

26. A: What are anterior air sacs? S2C06 Jeopardy Review Type of air sacs that push stale oxygen out of bird lungs

27. A: What is myoglobin? Diving mammals use this to store oxygen in the blood S2C06 Jeopardy Review

28. A: Blood and water move in opposite directions. As blood gains more oxygen, it encounters water with ever- higher concentrations of oxygen, so there is always a diffusion gradient.
