Across
  1. 3. clear fluid contained in blood that transports red and white blood cells, nutrients and waste
  2. 4. first 7 vertebrates
  3. 7. longer than their width, with hollow shafts for marrow, eg. femur
  4. 8. energy release for work, and growth and adrenaline production
  5. 12. narrowing of the coronary arteries of the heart or complete blockage of the coronary arteries leading to a heart attack.
  6. 16. is the movement which decreases the angle of a joint; for example, bending the elbow
  7. 18. muscle that relaxes to allow movement to take place
  8. 20. prime mover; the muscle that creates movemen
  9. 21. have no regular shape characteristics eg. bones in the face
  10. 22. 2nd 12 vertebrates
  11. 23. 4th 5 vertebrates
  12. 24. protection from diseases transfer of body heat
  13. 25. 5th 4 vertebrates
  14. 26. oxygen intake and carbon dioxide removal
  15. 28. creates movement by pulling on muscles, aids in digestion and breathing
  16. 29. same length and width eg. carpal bones in wrist
  17. 30. small bones developed in the tendons eg. the patellae in the knee
  18. 31. expelling of waste products
  19. 32. when the circumference of a muscle becomes larger as a result of exercise.
Down
  1. 1. short, long, irregular, sesamoid, flat
  2. 2. 3rd 5 vertebrates
  3. 5. muscle length changes while applying force.
  4. 6. living structures, capable of growth, adaption and repair
  5. 9. the process of one side of the muscle relalxing to let the other side the antagonist contract effectively
  6. 10. transport of materials to and from body cells
  7. 11. reproduction of the species
  8. 13. when a muscle produces force without changing length.
  9. 14. provide flat surface for attachment of muscles, enclose cavities for protection of organs eg ribs
  10. 15. provides nutrients for energy production
  11. 17. provides movement, shape, protection of vital organs
  12. 19. As we breathe in the air enters the lungs and travels into the alveoli . The capillaries surround the alveoli both have very thin walls that allow oxygen to pass from the higher-pressure alveoli to the lower-pressure capillaries. Once in the capillaries, oxygen binds to haemoglobin in red blood cells. The carbon dioxide in the capillaries is under higher pressure than the air in the alveoli during expiration. As we breathe out, carbon dioxide diffuses into the alveoli and is expelled.
  13. 27. delivers blood from the left ventricle of the heart to the rest of the body.
