True/False
Indicate whether the statement is true or false.
1. The period of ventricular contraction in the heart is called diastole.
2. The smallest branches of arteries are called arterioles.
3. Capillaries allow oxygen and nutrients to pass through to body cells.
4. Hypotension is high blood pressure.
5. Congestive Heart Failure occurs when the heart is weak and cannot pump blood efficiently.
6. The purpose of cardiac rehabilitation is to learn new things about the heart.
7. The red blood cells carry the oxygen in our blood.
8. During diastole, the atria are filling with blood and the ventricles contract.
9. The movement of the electrical impulse in the heart can be used to detect abnormal activity or disease.
10. Hemoglobin carries both oxygen and carbon dioxide.
11. Arteriosclerosis is a ballooning out of, or saclike formation on, an artery wall.
12. An embolus is a foreign substance circulating in the bloodstream.
13. Sickle cell anemia is a chronic, inherited anemia that occurs almost exclusively among African Americans.
14. Arrhythmias are abnormal heart rhythms and can be mild to life threatening.
15. Angioplasty may be used to remove or compress deposits in arteries, or to insert a stent to allow blood flow.
16. If hypertension is not treated, it can cause permanent damage to the heart, blood vessels, and kidneys.
