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