  1. 4. carries deoxygenated blood from the body to the heart

  3. 7. blood passes into this chamber before being pumped out through the aorta at high pressure
  4. 8. thin tissue that prevents the blood from flowing backwards between chambers and blood vessels
  5. 11. blood passes into this chamber before being pumped out into the pulmonary artery and the lungs
  6. 13. carries oxygenated blood from the heart to the body

  1. 1. thin tissue that prevents the blood from flowing backwards between two chambers
  2. 2. carries oxygenated blood from the lungs to the heart
  3. 3. the cells will contain lots of mitochondria to provide energy and they are myogenic (contract itself)
  4. 6. carries deoxygenated blood from the heart to the lungs
  5. 9. oxygenated blood from the lungs enters this chamber
  6. 10. Deoxygenated blood in the vena cava passes into this chamber under low pressure
  7. 12. these insert into the ventricle wall, are very tough and prevent the valves from turning inside out
