2. What is the name of the group of heart cells that sends out muscle contraction signals? 100

3. pacemaker 100

4. What is a flap of tissue that prevents blood from flowing backwards? 200

5. valve 200

6. What are the three main functions of the cardiovascular system? 300

7. 1.Delivering needed materials 2.Removing waste products 3.Fighting disease 300

8. How does the structure of the heart keep oxygen-rich and oxygen-poor blood from mixing? 400

9. A think wall called the septum is between the two ventricles. 400

10. What specific type of blood vessels take blood from the right ventricle to the lungs? Why type of blood is it carrying as it goes to the lungs? 500

11. pulmonary arteries oxygen poor 500

12. As blood moves away from the heart, does blood pressure usually increase or decrease? Why? 100

13. It decreases because the further the blood is from the pumping ventricles, the lower the force is. 100

14. 200 What is the big difference between the structure (layers) of an artery and a vein?

15. They both have an inner layer of epithelial cells, a middle layer of smooth muscle, and an outer layer of connective tissue. The big difference is that arteries have a thicker layer of smooth muscle, thus making them thicker overall. 200

16. 300 What is the name of the instrument used to measure blood pressure? (yes, the long one…)

17. 300 sphygmomanometer

18. Explain the process of diffusion. Don’t forget to also tell where it happens. 400

19. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. It occurs in the capillaries. 400

20. Name three ways that veins help continue to move blood onward back to the heart. 500

21. 1.Contraction of skeletal muscles 2.Larger veins have valves 3.Breathing movements exert pressure against veins in the chest

22. If your lymph nodes enlarge, what does that indicate? 100

23. Your body is fighting an infection. 100

24. What are the four components of blood? 200

25. 1.plasma 2.red blood cells 3.white blood cells 4.platelets 200

26. What type(s) of blood someone with type AB– can receive? 300

27. AB–, A–, B–, O– 300

28. Discuss what happens when you get cut. Be sure to use the terms platelets and fibrin. 400

29. Once cut, platelets collect and stick to the blood vessel. The platelets then release chemicals that start a series of reactions that produce a protein called fibrin. Fibrin weaves a net of tiny fibers across the cut. This net traps blood cells, thus forming a blood clot. 400

30. 500 What is hemoglobin? What is its job?

31. 500 It is an iron-containing protein that makes up most of the red blood cell. It’s job is to chemically combine with oxygen and carry it in the blood stream.

32. What is a heart attack? 100

33. A heart attack is when blood flow to part of the heart muscle is blocked. 100

34. What is the name of the condition where an artery wall thickens as a result of buildup of fatty materials? BONUS: spell it. 200

35. atherosclerosis 200

36. 300 Give three examples of foods that should be avoided to help prevent atherosclerosis.

37. 300 Red meats, eggs, cheeses, french fries, cream…

38. Hypertension is usually defined as what? (numerical answer) 400

39. 140 90 400 Greater than

40. Medications that help to lower cholesterol target what cholesterol producing organ in the body and slow down its production? 500

41. liver 500

42. What’s the difference between the job of a ventricle and an atrium? 100

43. Ventricles forcefully pump blood to the body while atria receive and pump blood to the ventricles. 100

44. How does atherosclerosis affect blood pressure? 200

45. As arteries narrow, blood pressure increases. 200

46. What is lymph? How does it return to the cardiovascular system? 300

47. Lymph is fluid inside vessels of the lymphatic system and consists of water, dissolved materials, and some white blood cells. It returns to the cardiovascular system through veins in the chest. 300

48. What is the universal blood donor? What is the universal blood recipient? 400

49. Universal Donor: O– Universal Recipient: AB+ 400

50. Who is Karl Landsteiner? 500

51. Scientist who discovered the 4 types of blood and determined which can be mixed together safely. 500

52. FINAL JEOPARDY Pulse

53. You take your pulse for 4 seconds and count 7 heart beats. What is your beats per minute?

54. 7 x 15 = 105 b.p.m.
