1.What does the pipette, the water, and balloon represent in this model of the circulatory system?

2.The action of applying pressure to and releasing pressure from the pipette demonstrates what function of the circulatory system?

3.What is a limitation of using this model as opposed to the human body?

4.Place a bean in the balloon, what does the bean represent?

5.What would happen if you squeezed water through the pipette leaving the bean in the balloon, how would the experiment be different?

Reinforcement:1.In your own words write the function for the

circulatory system.2.Rank the three main structures of the

circulatory system and give the reason for your rankings.

3.While running outside you stop to rest at a park bench, what happens to your heart rate while you are resting on the bench?

4.Using the scenario above how would the heart rates be different if we compared the rates of a 300 lb. woman to a 140 lb. woman? Explain your answer.
