27. Question 21 Figure A Figure C Figure B The diagram below shows 3 kinds of blood vessels in the circulatory system. Use this diagram to answer question 21.

28. Question 21 Figure B Which type of blood vessel does Figure B represent? • Alveolus • Artery • Capillary

29. Question 22 Which of these heart structures prevents blood from flowing backward (in the heart)? • Aorta • Coronary Artery • Valves

30. Question 23 After blood leaves the heart, what path does it follow through the blood vessels? • Arteries – Capillaries – Veins • Arteries – Veins – Capillaries • Capillaries – Arteries – Veins

31. Question 24 B A D C When the heart beats, which two chambers contract first? • Chambers A and B • Chambers A and C • Chambers B and D

32. Question 25 B A What is the function of chambers A and B? • To pump blood to the lungs. • To pump blood to the body. • To receive the blood that comes to the heart.

33. Question 26 If a person’s blood was missing white blood cells, what process could not take place? • Carrying glucose to cells. • Clotting of blood. • Fighting infections.

34. Question 27 What causes blood pressure? • The force with which the ventricles contract. • The rate at which blood flows through the heart. • The speed at which oxygen is added to the blood in the lungs.

35. Question 28 and 29 The graph below shows how blood pressure changes with age. Use this graph to answer questions 28 and 29.

36. Question 28 What can you conclude about blood pressure as people age? • It increases for men, not for women. • It increases for women, not for men. • It increases for both men and women.

37. Question 29 According to the graph, at what age would men and women probably have about the same blood pressure? • Below age 20 • Ages 30-34 • Ages 45-49

38. Question 30 Why is exercise important for cardio-vascular health? • It increases blood pressure. • It strengthens the heart muscle. • Reduces sodium in the blood.

39. Question 31 Why is atherosclerosis (fatty build up of artery walls) especially serious when it develops in the coronary arteries or the arteries that feed the heart tissue? • It can lead to a heart attack. • It can make red blood cells die. • It can then go on to affect the aorta.

40. Question 32 People who do not have enough iron in their diets sometimes develop a condition that affects hemoglobin. Which statement best describes the result of this condition? • The red blood cells cannot carry as much oxygen and you could be anemic. • The heart is weaker and cannot pump as much blood. • They have fewer platelets for clotting blood.
