Across
  1. 3. 1% of blood component
  2. 5. blood vessel that carries oxygen rich blood away from the heart
  3. 15. the only artery that carries oxygen POOR blood AWAY from the heart
  4. 16. a common heart defect that describes any misflow of blood through the heart
  5. 18. where red and white blood cells originate
  6. 19. the circulatory path that supplies oxygen RICH blood to and carries deoxygenated blood from the muscle tissue of the heart
  7. 20. disease-causing microorganisms that make you sick. ex. bacteria, fungi, viruses
  8. 24. red blood cells
  9. 26. where blood goes when returning to the heart from the rest of the body
  10. 28. where the blood leaves through on its way to the rest of the body
  11. 30. 55% of blood components
  12. 32. blood vessel that carries oxygen poor blood to the heart
  13. 33. foreign molecules that trigger an immune response in the body
Down
  1. 1. WBC that protect against pathogens by recognizing pathogens and kills them by producing antibodies. in the specific immune system
  2. 2. the smallest blood vessels. Gases and other substances are exchanged between the circulatory system and body tissues
  3. 4. where the blood leaves through on its way to the lungs
  4. 6. the valve on the left side of the heart
  5. 7. the circulatory pathway that carries oxygen-POOR blood from the heart to the lungs and oxygen-RICH blood from the lungs to the heart
  6. 8. two bottom chambers hat receive blood from the atria and pumps it into systemic/pulmonary circulation
  7. 9. the only vein that carries oxygen RICH blood TO the heart
  8. 10. AKA pacemaker. It sets the pace for cardiac activity
  9. 11. a block of bloodflow to the BRAIN
  10. 12. 44% of blood component
  11. 13. WBC that protects against pathogens by digesting them. In the general immune system
  12. 14. two top chambers that collect blood flowing into the heart
  13. 17. a general term to describe several conditions in which the walls of the arteries thicken, lose elasticity, and harden
  14. 21. protiens made by B CELLS that primarily bind to antigens on pathogens
  15. 22. where blood returns to after circulating through the lungs
  16. 23. the circulatory pathway that carries oxygen RICH blood from the heart to the body tissues and oxygen POOR blood from the tissues of the heart
  17. 25. a condition where there is a buildup of plaque on the inside of the artery walls. This causes them to narrow, and causes blood pressure to increase
  18. 27. a block of bloodflow to the HEART
  19. 29. the valve on the right side of the heart
  20. 31. white blood cells
