Across
  1. 3. separates the left and right atria
  2. 4. accepting de-oxygenated blood and propelling it to the lungs where it is oxygenated and its CO2 eliminated.
  3. 5. receives blood full of oxygen from the lungs and then empties the blood into the left ventricle
  4. 9. valve located between the upper left heart chamber (left atrium) and the lower left heart chamber (left ventricle)
  5. 12. valve between the left ventricle and the aorta to ensure that oxygen-rich blood does not flow back into the left ventricle
  6. 13. valve that controls the flow of blood from your heart's right atrium (top chamber) to the right ventricle (bottom chamber)
  7. 14. the muscular tissue of the heart
  8. 15. valve that lies between the right ventricle and the pulmonary artery
Down
  1. 1. the triangular wall of cardiac tissue that separates the left and right ventricles
  2. 2. The superior and inferior veins that go into the heart
  3. 6. receives oxygen-poor blood from the body and pumps it to the right ventricle
  4. 7. the main artery going into the heart and has a right and left coronary artery
  5. 8. the thin, smooth membrane which lines the inside of the chambers of the heart and forms the surface of the valves.
  6. 10. forces oxygenated blood through the aortic valve to be distributed to the entire body
  7. 11. the outer surface of the heart
