This is a model of a typical teenage heart with no defects. It has been coloured to show the two halves of the heart - blue representing the deoxygenated blood and red representing the oxygenated blood. In this model, you can also see the outline of the heart muscle (myocardium) around the ventricles and atria.
Model Printing Tips: Print the left (red) and right (blue) parts separate using a flexible material, then weave them together to get the most accurate model!
