If you love anatomy, or want to take your drawing skills to the next level, drawing realistic anatomy is an interesting challenge. Read this article to learn how to draw the internal structure of the human heart.
Step
Part 1 of 3: Finding the Diagram
Step 1. Find a good diagram by entering the sentence “Internal Structure of the Human Heart”
Choose an image that shows the entire heart, and click to enlarge it.
Step 2. Prepare a sheet of paper and drawing tools
Start with the pulmonary pulse. This pulse is in the lower left of the aorta, and there are two of them. Draw the upper pulse slightly smaller than the lower pulse.
Step 3. Sketch the lower part of the inferior vena cava below and slightly to the right of the pulmonary artery
Step 4. Start sketching the base/back of the heart, including the right and left ventricles, and the right and left atria
The pulmonary pulse should be adjacent to the right atrium and right ventricle.
Step 5. Change the chart if needed
If the diagram used to help you draw the heart, If you are still confused about the parts of the heart, look for a new diagram.
Part 2 of 3: Sketching the Heart
Step 1. Draw the other side of the pulmonary artery, and draw a circle at the end
Step 2. Start drawing with the pulmonary artery
Its lower end is above the right ventricle. The right and left sides should be slightly above the atrium and the pulmonary artery. The pulmonary artery is shaped like a large “T” that extends to the top of the right ventricle. Draw a circle at the bottom of the tip.
Step 3. To draw the aorta, start drawing the loop of the knot that goes around the pulmonary artery, and ends at the top of the left ventricle
To draw the back of the aorta, draw a line connecting the right side of the pulmonary artery to the top of the left atrium. Finish by drawing three nubs (cores) at the top of the vertices. Once done, remove the connecting line from one side of the base of the nub to the other. Dab a slanted circle at the top of the nub. Draw a circle at the bottom of the aorta, adjacent to the left ventricle.
Step 4. Draw a nub that extends from the top of the right atrium, covering the left side of the pulmonary artery, towards slightly above the left side of the pulmonary artery, to draw the superior vena cava
Draw a circle at the bottom of the superior vena cava, adjacent to the right atrium.
Step 5. Draw four circles on the left atrium, and one circle on the right atrium, slightly below the superior vena cava
Step 6. Draw the mitral valve between the two atria, and the aortic valve in the pulmonary and aortic arteries
Part 3 of 3: Coloring and Labeling Pictures
Step 1. Color the following sections with pink:
- Border
- Left porch
- Right porch
- Pulmonary blood vessels
Step 2. Color the following sections purple:
- pulmonary artery
- Left chamber
- right chamber
Step 3. Color the following sections blue:
- Superior Vena Cava
- Inferior Vena Cava
Step 4. Color the following sections with red:
Aorta
Step 5. Label the following sections:
- Superior Vena Cava
- Inferior Vena Cava
- pulmonary artery
- Pulmonary blood vessels
- Left chamber
- right chamber
- Left porch
- Right porch
- mitral valve
- Aortic Valve
- Aorta
- Pulmonary Valve (Optional)
- Tricuspid Valve (Optional)
Step 6. Title “Human Heart” above the image, to perfect your work
Tips
- Use a pencil
- Do not color the image until all diagrams are complete.
