Human Heart

Parents and teachers may want to examine a diagram of a human heart for kids for many reasons. It can be used as part of a lesson plan at school. Parents of children who need heart surgery may want to show the diagram so that the child understands more about the procedure.

How to Evaluate a Diagram

When you are looking for images for kids, you want to consider several factors before deciding whether to share it with the child, including:

  • The child's age
  • Maturity level
  • Level of detail in the diagram

For very young children, the best approach is to keep it simple. Choose a diagram that shows the heart from the outside and show another one that is a cross-section indicating the four chambers inside. If the child you want to share the diagram with is older, you can consider one that shows the four chambers of the heart, the valves and the veins and arteries that supply it.
