Circulatory System: Heart, Blood Vessels, and Blood

Making Blood...
  • Start with plasma (represented by yellow food coloring + water)
  • Add red blood cells (cheerios soaked in red food coloring + water)
  • Notice what happened to the color of blood!
  • Add white blood cells (white marshmellows)
  • Add platelets (tiny pieces of a peppermint marshmellow)
  • Notice how sticky the platelets are!







Pig Heart Dissection...

The heart is made up of cardiac tissue. We looked at the structure of the heart: right atrium, left atrium, right ventricle, left ventricle, aorta, and vena cava. We also discussed the function of the heart and the function of valves in the heart.
