j. a rapid heart rhythm, greater than 100 beats/min
k. carry oxygen - poor blood back to the heart
l. upper chambers of the heart
m. the bodys main artery
n. electrical impulses begin here
o. electrical impulses slow here to allow blood to move from the atria to the ventricles
p. a blood clot floating through blood vessels until it reaches a narrow area and blocks blood flow

Explanation:

1. Atria are the upper chambers of the heart, so 1 - L.
2. Coronary arteries supply blood to the myocardium, so 2 - C.
3. The atrioventricular node is where electrical impulses slow to allow blood to move from the atria to the ventricles, so 3 - O.
4. Myocardium is the heart muscle, so 4 - G.
5. The sinus node is where electrical impulses begin, so 5 - N.
6. Venae cavae carry oxygen - poor blood back to the heart, so 6 - K.
7. Ventricles are the lower chambers of the heart, so 7 - H.
8. Aorta is the body's main artery, so 8 - M.
9. Atherosclerosis is calcium and cholesterol buildup inside blood vessels, so 9 - B.
10. Dysrhythmia is an abnormal heart rhythm, so 10 - D.
11. Ischemia is decreased blood flow and poor oxygenation, so 11 - F.
12. Infarction is the death of tissue, so 12 - I.
13. Tachycardia is a rapid heart rhythm, greater than 100 beats/min, so 13 - J.
14. Asystole is an absence of heart electrical activity, so 14 - A.
15. Bradycardia is an unusually slow heart rhythm, less than 60 beats/min, so 15 - E.
16. Thromboembolism is a blood clot floating through blood vessels until it reaches a narrow area and blocks blood flow, so 16 - P.

Answer:

1. L. Upper chambers of the heart
2. C. Blood vessels that supply blood to the myocardium
3. O. Electrical impulses slow here to allow blood to move from the atria to the ventricles
4. G. Heart muscle
5. N. Electrical impulses begin here
6. K. Carry oxygen - poor blood back to the heart
7. H. Lower chambers of the heart
8. M. The body's main artery
9. B. Calcium and cholesterol buildup inside blood vessels
10. D. An abnormal heart rhythm
11. F. Decreased blood flow and poor oxygenation
12. I. The death of tissue
13. J. A rapid heart rhythm, greater than 100 beats/min
14. A. An absence of heart electrical activity
15. E. An unusually slow heart rhythm, less than 60 beats/min
16. P. A blood clot floating through blood vessels until it reaches a narrow area and blocks blood flow
