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. R T P 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
