Question

Gene uses a water pump and a plastic hose to model a human circulatory system. The pump pushes water through the hose, which represents a "vessel" in the system. The hose makes a complete loop and returns the water to the pump.

How is the model different from a real circulatory system?
A real circulatory system contains more than one "vessel."
A real circulatory system does not include a complete loop.
A real circulatory system pumps gas instead of a liquid.
A real circulatory system does not have a pump.
