Across
  1. 2. type of digestion that uses enzymes and acids to break down food
  2. 9. where water is reabsorbed, and all that is left is solid waste (feces)
  3. 10. system of the body that allows for involuntary movement (like digestion) and voluntary movement (like running) and includes skeletal, smooth and cardiac muscles
  4. 12. control center for the body
  5. 13. large type of cell that fights diseases and pathogens, numbers decrease when healthy
  6. 14. tiny sacs in the lungs that exchange gases with the blood
  7. 15. cell parts that cause blood clotting
  8. 18. the muscle that pumps blood throughout the body
  9. 19. cells that make up nerves
  10. 23. holds urine until evacuated from body
  11. 24. substances in food that provide the body with the materials needed to carry out functions
  12. 26. millions of these tiny filters in the kidneys
  13. 32. the smallest unit of life and the least complex level of organization
  14. 33. system of the body that breaks down food and absorbs nutrients
  15. 34. system of the body that protects, gathers information, eliminates waste, regulates temperature and produces vitamin D
  16. 36. inflate when one inhales and deflate when exhaling, the left is smaller than the right, take in oxygen and get rid of carbon dioxide
  17. 37. type of digestion that physically breaks down food
  18. 40. where digestion begins – chewing and chemicals in saliva
  19. 43. similar cells that are grouped together performing the same function
  20. 45. a lower chamber of the heart
  21. 48. blood vessel that carries blood away from the heart
  22. 51. a body structure made of different kinds of tissue that work together
  23. 53. where 90% of digestion and absorption of nutrients takes place
  24. 54. an upper chamber of the heart
Down
  1. 1. uses mechanical and chemical digestion to break down food
  2. 3. the condition in which an organism’s internal environment is kept stable regardless of changes in the outside environment (internally balanced)
  3. 4. connects bone to bone
  4. 5. liquid tissue that contains plasma and blood cells
  5. 6. a bundle of nerve tissue that connects the brain to the body
  6. 7. system of the body that provides support, protection of organs, aids in movement, and makes blood cells
  7. 8. system of the body that has 3 lines of defense to eliminate pathogens and maintain homeostasis
  8. 11. where two or more bones meet
  9. 16. thick tissue that separates the left side and right side of the heart
  10. 17. filter blood using nephrons
  11. 20. a group of organs that work together to perform major functions
  12. 21. type of cell that transports oxygen, nutrients and waste materials
  13. 22. largest organ, excretes waste and protects the body
  14. 25. muscle type that is voluntary and allows for movement
  15. 27. system of the body that gets rid of liquid and gas waste materials
  16. 28. system of the body that allows for gas exchange with the environment
  17. 29. blood vessels that carry blood back to the heart
  18. 30. largest bone in the body
  19. 31. makes blood cells
  20. 32. system of the body that moves blood and necessary materials for survival
  21. 35. muscle type that is involuntary and never gets tired
  22. 38. flexible material between bones that can absorb shock, limit friction and also provide structure
  23. 39. a response that initiates fever and the widening of blood vessels (swelling)
  24. 41. connects muscle to bone
  25. 42. system of the body that sends and receives messages, gathers / processes information about the environment and help maintain homeostasis
  26. 44. muscle type that is involuntary and can become tired over time
  27. 46. first line of defense that rids the body of pathogens by sneezing or coughing
  28. 47. tiny blood vessels that connect arteries and veins
  29. 49. muscle that assists the lungs with breathing – spasms during hiccups
  30. 50. the passageway for air
  31. 52. makes bile for digestion, makes urea for excretory system, and is the largest internal organ
