How to Draw a Heart Anatomy Diagram for Kids

1. Begin the heart anatomy diagram for kids outline by tracing its basic shape. Use curved lines to make an incomplete heart like shape with parallel lines extending above and below it.

Draw curved lines that meet at a point parallel to the bottom side to give the cross-section a three-dimensional appearance.

2. Use a series of overlapping curved lines to enclose a ring with three rectangular protuberances and a loosely "Y" shape. These are the aorta and the pulmonary artery.

3. Use curved lines to enclose rounded and "Y" shaped sections of the heart. These are valves, atriums, and ventricles. Then, use pairs of lines to draw arteries passing behind the heart.

4. Use curved lines to outline the right atrium and ventricles, as well as the interior of the vena cava.

5. Draw curved lines parallel to the sides of the pulmonary artery. Block of the ends of veins and vessels, and use curved lines to lend the atrium a circular shape.

6. Draw curved lines parallel to the sides of the aorta. Then draw cylinder-shaped veins on each side of the heart, using straight and curved lines.

7. Use straight and curved lines to outline arrows in the arteries, aorta, vena cava, atriums, and ventricles. This indicates the direction in which the blood flows.

8. Label your diagram with the words "The Human Heart."

9. Label the parts of the heart. Start with the inferior vena cava and work clockwise, labeling the right ventricle, right atrium, superior vena cava, aorta, pulmonary artery, left atrium, and left ventricle.

Draw small arrows showing the flow of blood in and out of the veins.

Starting at the bottom and working clockwise, label them "To lower body," "From lower body," "From right lung," "To right lung, "To upper body," "To left lung," and "From left lung."

Your heart anatomy diagram for kids outline is now complete. Color your picture. As a blood-filled muscle, hearts are typically red and pink. But to make the diagram easier to understand, use red for the parts carrying oxygenated blood and blue for the parts carrying oxygen-depleted blood.
