  14. 34. tube that connects the larynx (voice box) to the bronchi also called the windpipe
  15. 35. toxic waste produced by the breakdown of red blood cells
  16. 38. gland that produces adrenaline a hormone used to speed up heart rate and produce an extra burst of energy
  17. 41. process by which metabolic wastes are eliminated form the body
  18. 42. a protein that speeds up the rate of reactions (used to speed up digestion)
  19. 45. anything that enters the body and causes illness ex: virus, bacteria, fungi.
  20. 47. proteins found on cells that must match with a specific hormone in order to receive the message
  21. 49. a pair of fist sized organs, they remove excess water urea and metabolic wastes from the blood.
  22. 51. the process of nutrients moving from the digestive track into the blood
  23. 52. chemical substance than an organism needs to sustain life (examples: proteins, carbohydrates and lipids)
  24. 55. when the body can produce antibodies to attach to a pathogen and destroy it before the body is considered sick
  25. 56. process that requires oxygen
  26. 57. blood that does not contain oxygen
  27. 58. two large tubes in the chest that leads from the trachea to the lungs
  28. 59. tube connecting the mouth to the stomach
  29. 60. large muscular sac that continues the mechanical and chemical digestion of food
  30. 62. contractions of smooth muscles that provide the force that moves food through the digestive system
  31. 63. sac like organ in which urine is stored
  32. 65. type of blood cell that guards against infection, fights parasites and attacks bacteria
  33. 66. blood containing oxygen
Down
  1. 1. process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
  2. 2. organ of the digestive track where chemical digestion and absorption of nutrients happen
  3. 3. process that does not require oxygen
  4. 5. a group of drugs used to kill of bacteria when someone is already infected.
  5. 6. produces bile which helps the breakdown of fats
  6. 8. largest organ that helps in both protecting the body and releasing wastes such as excess water, salt and sweat.
