Big idea

Using a simple model of the heart that they create, students experiment with the function of the heart chambers and valves to circulate blood.

In the Film

In Superhuman Body, doctors utilize pig heart valves to repair proper valve function in human hearts. This procedure shows us the precise mechanics necessary for maintaining a muscle that must work properly 24/7 to keep a person alive. This activity will further explain the function of these valves as well as the timing required to operate the heart.

Objectives

  1. Students will construct a model of heart valves using simple materials.
  2. Students will demonstrate the function of the heart chambers and valves to circulate blood.
  3. Students will use their constructed model to simulate blood flow through the chambers by working collaboratively, some students pump the chambers while other students control the opening and closing of valves.
