CIRCULATORY SYSTEM STATIONS ACTIVITY
Station 1
1. Label each part of the heart marked by a letter.
2. What is the function of the thick-walled structure labeled I?
3. What is the function of the thin-walled structure labeled D?
4. What is the function of E and C?
5. How is the blood in part A different from the blood in part F?
6. How is the blood in part F different from the blood in part G?
Station 2
7. Add arrows to show the direction of blood flow around the body.
8. Using red and blue pencils, show where blood is high in oxygen (red) and where
blood is low in oxygen (blue). At some intermediate stage, let the red and blue
paths overlap to appear purple.
9. Label the superior vena cava, inferior vena cava, capillaries, aorta, pulmonary
vein, and pulmonary artery.
10. Label the pulmonary circuit and systemic circuit.
Station 3

20. Which type of vessel ALWAYS carries oxygenated blood? Circle the correct
answer(s).

Station 4
22. What is a normal blood pressure reading?
23. Read the statistics about the individuals below, and classify each individual as having
an average blood pressure, high blood pressure, or low blood pressure.
Nikola has a blood pressure of 110/70. Her
average heart rate is 72 beats per minute.
In addition, the average stroke volume for
her heart is 69 ml of blood per beat.
Panos has a blood pressure of 120/80. His
average heart rate is 65 beats per minute,
and his average stroke volume is 70 ml of
blood per beat.
Olga has a blood pressure of 130/80. Her
average heart rate is 70 beats per minute,
and her average stroke volume is 65 ml of
blood per beat.
Apostolos has a blood pressure of 140/85.
His average heart rate is 75 beats per
minute, and his average stroke volume in
65 ml of blood per beat.
24. Calculate the cardiac output for each individual.
25. Use the blood pressure cuff to measure your blood pressure. Record your blood
pressure here:
___________/___________
26. What do each of these numbers from the blood pressure reading represent?
Station 5
Obtain an envelope labeled “Path of Blood Scramble”. Put the pieces from the envelope
in the correct order to represent the path of blood through the circulatory system.
Technically, it doesn’t matter where you start because it is a cycle! When you think you
have the correct order, call the teacher over to have her check it. You only get one shot at
getting it right, so don’t ask to have it checked until you have your final answer!
Station 6
Examine the dissected calf heart. Identify the parts that are labeled with pins.
