Does anatomy fascinate you or do you just want to improve your artistic skills? Drawing anatomical parts in a realistic way can be very difficult. Follow the steps below to draw the internal structure of the human heart.
Steps
Part 1 of 3: Finding a Figure
Step 1. To find a good figure, go to Google Images and type “internal structure of the human heart”
Find an image that shows the heart in its entirety and click on it to enlarge it.
Step 2. Get a piece of paper and something you can draw with
It begins with the pulmonary veins, which are located in the lower left of the aorta. There are two; draw the upper vein a little smaller than the lower one.
Step 3. Begin sketching the lower part of the inferior vena cava below the pulmonary veins, slightly to the right
Step 4. Start drawing the base of the heart, including the right ventricle, left ventricle, right atrium and left atrium
The pulmonary veins must be adjacent to the right atrium, while the inferior vena cava must be adjacent to the right atrium and right ventricle.
Step 5. If necessary, change the figure
If the image you are using helps you in the realization of the drawing, continue to use it. But if you can't understand how the parts of the heart are positioned, look for another figure.
Part 2 of 3: Drawing the Heart
Step 1. Draw the other side of the pulmonary veins and add circles at the end
Step 2. Start drawing the pulmonary artery
The lower part ends at the upper part of the right ventricle. The right side and the left side should be slightly above the atria and pulmonary veins. The pulmonary artery has a "T" shape and extends to the upper part of the right ventricle. Draw a circle at the end.
Step 3. To draw the aorta, start from the arch positioned above and around the pulmonary artery, which ends in the upper part of the left ventricle
To create the posterior part of the aorta, draw a single line that connects the right side of the pulmonary artery with the upper part of the left atrium. Finally, draw three protuberances in the upper part of the arch, then erase the lines left at the base of the protuberances. Add slanted circles to the top of each bump. Draw a circle in the lower part of the aorta, next to the left ventricle.
Step 4. To draw the superior vena cava, draw a protuberance that extends from the upper part of the right atrium, overlaps the left side of the pulmonary artery and passes just above the left side of the latter
Draw a circle at the bottom of the superior vena cava, next to the right ventricle.
Step 5. Draw four circles in the left atrium and one in the right atrium, just below the superior vena cava
Step 6. Draw the mitral valves between both atria and the aortic valves both in the pulmonary artery and in the aorta
Part 3 of 3: Coloring and Labeling
Step 1. Paint pink:
- The contour
- The left atrium
- The right atrium
- The pulmonary veins
Step 2. Color in purple:
- The pulmonary artery
- The left ventricle
- The right ventricle
Step 3. Color blue:
- The superior vena cava
- The inferior vena cava
Step 4. Color red:
The aorta
Step 5. Be sure to write the names of these parts:
- Superior vena cava
- Inferior vena cava
- Pulmonary artery
- Pulmonary veins
- Left ventricle
- Right ventricle
- Left atrium
- Right atrium
- Mitral valves
- Aortic valves
- Aorta
- Pulmonary valve (optional)
- Tricuspid valve (optional)
Step 6. Finally, write “The Human Heart” above the drawing
Advice
- Use a pencil.
- Start coloring only when you have drawn the entire figure.
