Cardiovascular System Test Review Key
1. Pericardium (loose fitting sac around heart) and epicardium (covers surface of the heart)
2. The take blood away from the heart to other organs. All of them except the pulmonary artery take
oxygenated blood to other parts of the body.
3. Superior and Inferior vena cavae
4. At 4 weeks
5. Capillaries
6. To measure blood pressure
7. Interventricular septum
8. An EKG or ECG reading.

Q
S
P =Depolarization (Contraction) of the atria
QRS = Depolarization (Contraction) of the ventricles
T = Repolarization (Relaxing) of the ventricles
9. Inflammation of the pericardium due to inflammation, linings of the heart stick together.
10. Bundle of His
11. An abnormal sound that identifies the leakage of blood through the heart valves in the wrong
direction.
12. Blood pressure
13. SA node
14. An opening between the left and right atria in the heart of the unborn baby. This closes when the
baby takes its first breath.
15. Tricuspid valve
16. Near the apex or ‘left point’ of the heart
17. Superior vena cava
Right atrium
Tricuspid valve
Right ventricle
Pulmonary valve
Pulmonary artery
Lungs – take up O2 and give off CO2
Pulmonary veins
Left atrium
Bicuspid valve/Mitral valve
Left ventricle
Aortic valve
Aorta
18. 120/80
19. A heart attack
20. C
21. Auricles
22. Coronary artery
23. Systolic
24. In the mediastinum, behind the sternum and resting on the diaphragm
25. Between the left atrium and the left ventricle
26. Epicardium
27. They are ‘half- moon’ shaped
28. Top = atria, Bottom = ventricles
29. Arteries – take blood away from the heart
Veins – take blood to the heart
Thick muscle and elastic fibers
Thinner walls, but larger diameter
No valves
Valves that allow blood to flow in one
Direction
Usually carry oxygenated blood
Usually carry deoxygenated blood
(Exception is pulmonary artery)
(Exception – pulmonary veins)
30. It lowers
31. 1. Aorta/Aortic arch
2. Superior vena cava
3. Right pulmonary artery
4. Right pulmonary veins
5. Right atrium
6. Tricuspid valve
7. Right ventricle
8. Inferior vena cava
9. Left pulmonary artery
10. Left pulmonary veins
11. Left atrium
12. Bicuspid valve/Mitral valve
13. Aortic valve
14. Left ventricle
15. Descending aorta
