Unit 5 Activity 2

2. Failure A chronic condition where the heart cannot pump blood efficiently.
5. An irregular or abnormal heartbeat rhythm.
6. Blood Pressure
10. Monitor A portable device worn by patients to continuously record ECG data for 24–48 hours.
12. The central muscular organ that pumps blood.
15. High-pressure vessels that carry oxygenated blood away from the heart.
17. Congestive Heart Failure
19. The classic blood pressure cuff used to measure arterial pressure.
22. Coronary Artery Disease
24. The buildup of fats, cholesterol, and plaque in the artery walls.

1. Chronically elevated blood pressure forces the heart to work harder.
3. Microscopic vessels where gas and nutrient exchange occurs.
4. (Prefix): Means fast (e.g., tachycardia).
7. The thick, muscular middle layer of the heart wall.
8. (Suffix): Means hardening (e.g., arteriosclerosis).
9. Vessels that return deoxygenated blood back to the heart.
11. Records the electrical activity of the heart over time.
13. Uses ultrasound waves to create images of heart valves and chambers.
14. (Prefix): Means slow (e.g., bradycardia).
16. Catheterization Inserts a thin tube into blood vessels to visualize blockages.
18. Deep Vein Thrombosis
20. (Root): Relates to blood vessels (e.g., angiogram).
21. Infarction A heart attack, caused by blocked blood flow to the heart muscle.
23. Cardiopulmonary Resuscitation
25. (Root): Relates to the heart (e.g., cardiology).
