Across
- 2. blood from the digestive system, spleen and pancreas is carried to the lives by the hepatic portal vein
- 3. the middle cavity of the thorax
- 5. connect arterioles and venules
- 8. slow heart rate
- 9. lines heart chambers
- 11. a recording of the flow of electrical impulses that travel through the heart
- 13. carry blood toward the heart
- 16. septum that divides the heart longitudinally (between the ventricles)
- 19. means “contraction”
- 20. carry blood away from the heart
- 21. The pressure of blood pushing against the inner walls of blood vessels
- 24. visceral pericardium
- 26. prevents flaps from blowing up into the atria when ventricles are contracting
- 28. Includes the events in one heartbeat
- 31. surrounds the serous membrane
- 34. Blood flow through coronary arteries that supply the heart is limited due to atherosclerosis, a build up of plaque
- 35. also known as the tricuspid valve
Down
- 1. rapid heart rate
- 4. occurs when blood flow is blocked by a blood clot
- 6. septum that divides the heart longitudinally (between the atria)
- 7. pulmonary, aortic
- 10. starts with damage to the endothelium often caused by: hypertension, high cholesterol, smoking, and high blood sugar
- 12. (Inferior end) points toward the left hip and rests on the diaphragm
- 14. occurs when a vessel breaks and there is bleeding on the brain
- 15. heart attack
- 17. thick muscular layer around the heart wall
- 18. (Superior end) points toward the right shoulder
- 22. a measure of heart rate by counting the pressure waves created by contraction of the ventricles
- 23. protects the brain by providing more than one route for blood to reach brain tissue
- 25. upper chambers, receive blood
- 27. lower chambers, discharge blood
- 29. blood supply to the myocardium itself is provided by the coronary arteries
- 30. amount of blood pumped out by each side of the heart in one minute
- 32. high blood pressure
- 33. means “relaxation”
