Across
  1. 3. Thick,fibrous membrane that surrounds the heart.
  2. 7. Number of cardiac contractions per minute.
  3. 9. The largest and shortest myocardial blood vessels. Rapidly divides into the laft anterior descending artery and the circumflex artery.
  4. 12. TIP of Heart
  5. 14. vessel that returns venous blood back to heart.
  6. 15. TOP of Heart
  7. 16. Valves of the heart through which blood flows through from the atria to the ventricles.
  8. 19. Middle layer of heart wall made mostly of cardiac muscle tissue.
  9. 20. Layer of serous pericardium that lies closelt agaisnt the heart; also called the visceral pericardium.
Down
  1. 1. Returns oxygenated blood from lungs to right atria.
  2. 2. Delivers unoxygenated blood from right ventricle to lungs.
  3. 4. Provides oxygenated blood to the right side f the heart muscle.
  4. 5. Period of relaxation in which the heart chambers are allowed to fill.
  5. 6. Specialized bands of tissue inserted between myocardial cellsthat increase the rate in which the action potential is spread from cell to cell.
  6. 8. Amount of blood pumped out by either ventricle in a single cardiac contraction.
  7. 10. Half-moon shaped valves that seperate the heart from the aorta and pulmonary arteries.
  8. 11. The amount of blood that is pumped by the ventricles in 1 minute.
  9. 13. The percentage of blood that leaves the heart each time it contracts.
  10. 17. Membrane that lines the inside of the heart.
  11. 18. Delivers oxygenated blood from left ventricle to the body.
