Across
  1. 4. largest artery
  2. 5. valve between the left atrium and the left ventricle; bicuspid valve
  3. 6. this blood is bright red blood that has picked up oxygen from the lungs, and enters back into the heart through the pulmonary lungs
  4. 7. the two lower chambers of the heart, and they pump blood out to the lungs and body
  5. 8. a double layered protective covering of the heart
  6. 10. vessels that carry blood towards the heart
  7. 11. smallest blood vessels
  8. 15. chamber that receives blood from the lungs
  9. 16. the vena cava where blood returns to the heart from upper body
  10. 18. deoxygenated blood enters the heart here
  11. 19. valve between the right atrium and the right ventricle
  12. 21. sends deoxygenated blood to the lungs
  13. 23. vessels that carry blood away from the heart
Down
  1. 1. pumps blood out of the heart through the aorta aortic valve into the aorta
  2. 2. sends oxygenated blood back to the heart
  3. 3. the body system that includes the heart and blood vessels
  4. 9. this blood enters on the right side of the heart through the superior and inferior vena cava and leaves through the pulmonary artery to the lungs
  5. 12. the two upper chambers of the heart
  6. 13. prevent back flow of blood
  7. 14. vena cava where the blood returns to the heart from lower body
  8. 17. pumps oxygen poor blood to the lungs through the pulmonary valve then the pulmonary arteries
  9. 20. valve positioned between the right ventricle and the pulmonary artery
  10. 22. valve that keeps blood from flowing back into the left ventricle
