Cardiovascular Terminology
Across
- 7. CIRCULATION the part of systemic circulation that provides the heart muscle with oxygen and nutrients and carries away waste products
- 8. a portion of a thrombus that breaks off and moves through the bloodstream.
- 10. the constriction of the muscular wall of an artery to increase blood pressure.
- 11. the widening of the muscular wall of an artery to decrease blood pressure
- 15. the middle and thickest layer of the heart. It is made primarily of cardiac muscle.
- 16. a membrane that covers the heart and large blood vessels attached to it.
- 18. the outermost layer of the wall of the heart.
- 20. PRESSURE the blood pressure measured when the left ventricle of the heart contracts.
Down
- 1. NODE a small bundle of heart muscle tissue in the superior wall of the right atrium that sets the rhythm of the heart’s contractions.
- 2. OF HIS this is the node located between the ventricles of the heart that carries the electricl impulse from the AV node to the bundle branches.
- 3. NODE node that is located between the atria of the heart. After the electrical impulse reaches the atrioventricular node, the atria contract and the impulse is sent to the ventricles.
- 4. thickness
- 5. CIRCULATION the circulation of blood through the arteries, capilaries and veins of the general system, from the left ventricle to the right atrium.
- 6. the innermost layer of the heart.
- 9. an abnormal narrowing of a body passage
- 12. TENDINEAE cord-like structures that attach the cusps of the heart valves to the papillary muscles in the ventricles.
- 13. PORTAL SYSTEM the collection of veins carrying blood to the liver.
- 14. OUTPUT the product of heart rate and stroke volume, measured in liters per minute; the amount of blood that is pumped by the heart in 1 minute.
- 16. FIBERS cardiac fibers that are located in the lateral walls of the ventricles.
- 17. CIRCULATION the passage of blood from the right ventricle through the pulmonary artery to the lungs and back through the pulmonary veins to the left atrium.
- 19. PRESSURE the blood pressure measured when the heart relaxes.
