c. Veins
d. Lymphatic ducts
2. These
a.

d. Nutrients
5. This diagram shows how the respiratory system maintains proper balance of carbon
dioxide in the body. Starting at the lower left picture of cells in the body, describe what
happens to carbon dioxide levels and how the body responds.
Start Here:

affect on CO2 levels?:
1 – body cells:
2. – Blood chemistry:
3. – Brain:
4. Respiratory response:
6. Respiration rate is controlled by:
a. Carbon dioxide and the medulla oblongata
b. Oxygen and the hippocampus
c. The heart and need for air
d. Low acidity and the brain
7. If the diaphragm does not function properly:
a. Gas exchange between oxygen and carbon dioxide will not occur
b. The lungs will not be able to take in enough oxygen or expel enough CO2
c. Not enough air will get into the bronchi
d. The breathing rate will become dangerously high

pulmonary artery
19. Pulmonary artery and pulmonary vein carry blood:
a. Between the heart and body cells
b Between the heart and lungs
c. To the heart from the body cells
d. Away from the heart and to the lungs
20. The right atrium and right ventricle:
a. are high in oxygen
b. are low in oxygen
c. pump blood to the lungs
d. Lead to the aorta
21. Mr. Love went hiking and discovered that he got very tired. Explain why Mr. Love should
start doing some exercise for his heart:
Calculate Mr. Love’s target rate zone – assuming he is 45 years old:
a. Max rate:
b. Upper zone rate:
c. Lower zone rate:
d.Mr. Love starts to do some running on a treadmill. He’s pumped because his heart rate is
speeding along at 150 BPM. What do you tell Mr. Love about the effectiveness of his exercise
and his heart?
e. Explain in a paragraph how Mr. Love’s heart and respiratory system work
together, and why a strong heart is important
