Across
- 3. inflammation of the lining of the heart
- 6. measures the electric activity of the heart to detect underlying heart conditions
- 8. heart valve that separate the left atrium from the left ventricle
- 9. heart muscle
- 11. type of blood vessels that carry oxygenated blood away from the heart; thick, muscular walls
- 13. irregular heart rate and rhythm
- 14. organ that propels blood throughout the circulatory system;size of one's fist and weighs about 10.5 oz
- 15. How many chambers are there?
- 19. septum that divides the right and left ventricles of the heart
- 22. branch off from the arteries and carry oxygenated blood to the capillaries
- 23. large blood vessels that return deoxygenated blood from the body to the heart; walls are less muscular than the walls of arteries
- 25. circulation that supplies the heart muscles
- 26. lining that surrounds the heart
- 28. blood clot in vein
- 29. heart valve that separates the right atrium from the right ventricle
- 30. circulation that carries highly oxygenated blood from the left side of the heart to all the tissues of the body and back to the heart
Down
- 1. phase of the cardiac cycle that occurs when the heart is in a state of relaxation and dilation (expansion) and blood is refilling in the chambers
- 2. known as a heart attack
- 4. disease of the heart muscles; referred to as "enlarged heart"
- 5. circulation that transports deoxygenated blood from the right side of the heart to the lungs; returns oxygenated blood to the left side of the heart
- 7. high blood pressure
- 10. heart valve that separates the left ventricle from the aorta
- 12. surgical procedure done when there is narrowing or blockage of a coronary artery
- 16. phase that occurs when the ventricles contract sending blood to the pulmonary and systemic circulation
- 17. heart valve that separates the right ventricle from the pulmonary artery
- 18. smallest and thinnest of the blood vessels; where O2, CO2, nutrients and waste are exchanged between blood and tissue cells
- 20. a chamber of the heart that receives blood from the veins and forces it into a ventricle or ventricles
- 21. part of a particle,air, fluid, or part of a blood clot that travels through the blood vessel leading to blockage of the vessel
- 24. smaller veins that collect blood from the capillaries and return it to the larger veins
- 27. septum that divides the right and left atria of the heart
