Here are the definitions for the medical terms listed on your worksheet:

1. atrioventricular defect: A hole in the wall (septum) that separates the upper chambers (atria) and lower chambers (ventricles) of the heart, allowing blood to mix where it shouldn’t.

2. bacterial endocarditis: An infection of the inner lining of the heart (endocardium), usually caused by bacteria entering the bloodstream and attaching to damaged heart tissue or valves.

3. myocarditis: Inflammation of the heart muscle (myocardium), often caused by a viral infection, which can weaken the heart’s ability to pump.

4. pericarditis: Inflammation of the sac surrounding the heart (pericardium), which can cause chest pain and sometimes fluid buildup around the heart.

5. angiocardiitis: Inflammation affecting both the blood vessels (angi-) and the heart (-carditis). This term is less commonly used but refers to combined inflammation of these structures.

6. angiostenosis: Narrowing of a blood vessel due to thickening or hardening of its walls, which reduces blood flow.

7. aortic stenosis: Narrowing of the aortic valve in the heart, making it harder for blood to leave the left ventricle and go out to the body.

8. arteriosclerosis: Hardening and thickening of the arteries’ walls, reducing their flexibility and restricting blood flow — this is a general term.

9. atherosclerosis: A specific type of arteriosclerosis where fatty deposits (plaque) build up inside the arteries, narrowing them and increasing risk of heart attack or stroke.

10. tachycardia: A faster-than-normal heart rate — typically over 100 beats per minute at rest in adults.

11. hypertension: High blood pressure — when the force of blood against artery walls is consistently too high.

12. hypotension: Low blood pressure — when blood pressure is lower than normal, which may cause dizziness or fainting.

13. hematosis: The process of forming blood cells; also called hematopoiesis. It happens mainly in the bone marrow.

14. bradycardia: A slower-than-normal heart rate — typically under 60 beats per minute at rest in adults.

15. cardiomegaly: Enlargement of the heart, which can be caused by conditions like high blood pressure, valve problems, or cardiomyopathy.
