Medical Terminology

2. a test that records the electrical activity of the heart.
3. / o: Refers to veins.
7. Heart Defects: Structural defects in the heart that are present at birth.
8. Occurs when blood flow to the brain is interrupted, causing damage or death of brain cells.
9. / o: Refers to the heart.
11. Artery Disease (CAD): Narrowing or blockage of the arteries that supply blood to the heart muscle.
13. A muscular organ that pumps blood throughout the body. It has four chambers: two atria and two ventricles.
15. catheterization: an invasive procedure that provides a detailed look at the coronary arteries.
17. Vessels that carry oxygen-rich blood away from the heart. They have thick, muscular walls.
19. The fluid connective tissue that circulates through the vessels, carrying essential substances like oxygen, nutrients, hormones, and waste products.
20. magnetic resonance imaging: highly detailed images of the heart using magnets and radio waves.
22. a heart attack.

1. Abnormal heart rhythms, such as atrial fibrillation or tachycardia.
2. : a non-invasive test that uses sound waves to create a moving picture of your heart.
4. test: test that measures how your heart performs under physical activity
5. Failure: A condition where the heart cannot pump blood effectively enough to meet the body's needs.
6. quick, non-invasive test that records the heart's electrical signals
7. a narrowing of the arteries that supply blood to the heart.
10. / o: Refers to arteries.
11. a condition where the heart cannot pump blood effectively.
12. an enlargement of the left ventricle, the main pumping chamber of the heart.
14. Vessels that carry deoxygenated blood back to the heart. Their walls are thinner than those of arteries.
16. Tiny, microscopic blood vessels that connect arterioles and venules. Their thin walls allow for the exchange of oxygen, carbon dioxide, nutrients, and waste between the blood and tissues.
18. / o: Refers to a blood clot
21. / o: Refers to blood vessels.
