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