Answer 1

Here are the answers filled in:

Page 1
1. diaphragm
2. down; expand (fill with air)
3. oxygen
4. Oxygen
5. food (glucose)
6. lungs
7. alveoli (tiny air sacs)
8. a tennis court
9. spread out (how much surface area something has)
10. alveoli
11. right; left lung
12. 3; 2
13. Because the heart takes up space on the left side of the chest.
14. lactic acid

15. respiration; ATP
16. ATP; a sort of battery / energy currency
17. stores; uses
18. contracts (moves down) and air rushes in
19. It moves up (relaxes) and air is pushed out (you exhale).
20. mucus, which traps dust and germs and keeps them from reaching the lungs.
21. tar and nicotine
22. perform cellular respiration (use oxygen to make energy)
23. can’t; oxygen; gills
24. carbon dioxide; gills
25. about 10^22 molecules (on the order of 10 billion trillion molecules)

Review
1. Diaphragm
2. Oxygen and food (glucose)

3. Alveoli
4. Left; because the heart is on the left side, so the left lung is smaller.
5. A smoker’s lung is darker/blackened and coated with tar; a healthy lung is pink and spongy.
6. Exercise regularly, don’t smoke, eat well, and breathe clean air.
7. Lactic acid buildup in the muscles.
8. ATP stores and supplies energy for cellular processes (the cell’s energy currency).
9. Mucus (and nose hairs/cilia) trap dust and particles and sweep them out.
10. Tar (and also nicotine and carbon monoxide)
11. Both use oxygen to produce energy and release carbon dioxide (both perform gas exchange for cellular respiration).
12. Fish extract dissolved oxygen from water with gills; humans take oxygen from air with lungs.
13. food + oxygen ---> carbon dioxide + water + energy (food + oxygen -> CO2 + H2O + energy)
