7. TRUE OR FALSE. The majority of Americans aged 65-74 years report that tare physically inactive.
8. TRUE OR FALSE About half of Americans who have never graduated from high school report that they are not regularly physically active.
9. TRUE OR FALSE. Approximately four percent more American women report physical inactivity than do men.
10. TRUE OR FALSE. We can conclude from this data that the more educated one is, the more physically fit they are.
Station C

11. Identify the labeled chamber (be specific).
12. What vessel(s) serve the chamber that you identified in question #11?
13. Identify the labeled vessel.
14. What chamber of the heart does the vessel you identified in Question #13 serve (be specific)?
15. What valve does the blood pass through in traveling from chamber (Question #14) to vessel (Question #13)?
Station D
16. The proper name for the blood pressure cuff is .
17. As the cuff is released during blood pressure measurement, characteristic sounds are heard that represent the turbulent flow of blood through the constricted artery. These sounds are called .

Tricuspid valve
Pulmonary artery
Pulmonary vein
Left ventricle
Station G
MATCHING:
31. tachycardia A. Period of ventricular contraction.
32. bradycardia B. A heart rate over 100 beats per minute.
33. fibrillation C. Irregular heart contractions.
34. systole D. A slower than normal heart rate.

Station H
Two different breakfast cereals are represented below:
Cereal A Cereal B
120 Calories/serving 120
160 Calories/serving 160
With 1/2 cup fat free milk*
1 cup Serving size 3/4 cup
0 g fat/serving 26
28 g carbohydrates/serving 26
3 g protein/serving 1
*1/2 cup of fat free milk contributes 40 calories, 6 g of carbohydrates, and 4 g of protein.
For breakfast every day, Jeremy eats one cup of Cereal B with one cup of fat free milk.
His sister Kaly eats 1 1/2 cups of Cereal B without milk.
His mother Linda mixes 1/2 cup of Cereal A with 1/2 cup of Cereal B, and eats the mixture with one cup of fat free milk.
REFER TO THE INFORMATION PROVIDED:
36. Which family member consumes the most grams of fat per meal?
37. How many Calories does Jeremy consume, including milk?
38. How many calories does Linda consume?
39. Which family member consumes the most grams of carbohydrate per meal?
40. Which family member consumes the least amount of Calories per meal?
Station I

42. Which of the labels (A,B,C,D) correctly identifies the inspiratory reserve volume?
43. What, in ml, is the total lung capacity?
44. What, in ml, is the tidal volume?
45. Using the labels on the spirogram, vital capacity can be identified as:
Station J
