7. A blood clot occludes or plugs up some part of a coronary artery.
8. Flow from the left ventricle of the heart through the blood vessels to all parts of the body and back to the right atrium of the heart.
11. Deflection on an ECG that occurs as a result of depolarization of the ventricles.
13. Vessel carrying blood toward the heart.
15. Describes the electrical activity that triggers contraction of the heart muscle.
17. Tiny vessels that connect arterioles and venules.
19. The sound heard when pumping blood.
21. Covering of the heart.

1. Severe chest pain that occurs when the myocardium is deprived of adequate oxygen.
2. Vessel carrying blood away from the heart.
3. Contraction of the heart.
4. Two bottom chambers of the heart.
5. Relaxation of the heart.
6. Blood flows through vessels that are arranged in a complete circuit or circular pattern.
9. Measures the heart's electrical activity.
10. Name of the valve inbetween the right atrium and left ventricle.
12. Inflammation of the endocradium lining.
14. Is the pressure or “push” of blood as it flows through the cardiovascular system.
16. Name of the valve inbetween the left atrium and left ventricle.
18. Deflection on an electrocardiogram that occurs with repolarization of the ventricles.
20. Deflection on an ECG that occurs with depolarization of the atria.
