You like drawing and you are used to sketching landscapes, portraits, etc. Have you ever tried to sketch part of an individual's anatomy? If you are curious to get started, start with the heart.

Steps

Part 1 of 3: find a representation of a heart

Draw the Internal Structure of the Heart Step 1

Step 1. Look for a model

Go to your search engine and type in "diagram of a human heart". Then browse through the images and select the one that clearly shows the details.

Draw the Internal Structure of the Heart Step 2

Step 2. Obtain what you need to draw

Take a sheet of paper and a gray pencil. Start sketching the two pulmonary veins. They are located below on the left of the aorta. Remember to make the lower vein a little larger than the upper vein.

Draw the Internal Structure of the Heart Step 3

Step 3. Bite the inferior vena cava

Draw the inferior vena cava a little bit to the right below the pulmonary veins.

Draw the Internal Structure of the Heart Step 4

Step 4. Make the base of the heart

Sketch the right and left ventricles and atria to form the base of the heart. Make the pulmonary veins glued to the inferior vena cava. Just as the latter must be against the right ventricle and the right atrium.

Draw the Internal Structure of the Heart Step 5

Step 5. Change the pattern as needed

If your image of the heart is a great help to you in sketching the different parts of it, continue with this sketch. However, if you cannot properly visualize the anatomy of the heart, search for a new image.

Draw the Internal Structure of the Heart Step 6

Step 1. Make the other part of the veins

On your drawing, draw the other side of the pulmonary veins and finish with circles.

Draw the Internal Structure of the Heart Step 7

Step 2. Start with the pulmonary artery

The lower part reaches up to the top of the right ventricle. Its right and left sides should be a little above the pulmonary veins and atria. The pulmonary artery looks like a big capital "T". Consider finalizing the base of the artery with a circle.

Step 3. Draw the aorta

Start by sketching a curve above the pulmonary artery that surrounds it. This curve should arrive at the top of the left ventricle. To make the top of the aorta, curve from the right side of the pulmonary artery that ends at the top of the left atrium. Finally, on the top of the aorta make three small chimneys. Then, erase at the base of the three small chimneys the parts of the line materializing the aorta and round the top of each chimney. Remember to finish the lower part of the aorta with a circle, glued to the left ventricle.

Step 4. Sketch the superior vena cava

Draw a straight tube that starts at the top of the right atrium, then continues to the left side of the pulmonary artery and ends a little above the latter. To finalize, create a circle at the base of the superior vena cava and at the level of the top of the right atrium.

Draw the Internal Structure of the Heart Step 10

Step 5. Finalize the left and right ear cups

Make four small circles on top of the left atrium and one circle on top of the right atrium, just below the superior vena cava.

Draw the Internal Structure of the Heart Step 11

Step 6. Sketch the last valves

Draw the mitral valves that are located between the two atria, then make the aortic valves at the aorta and pulmonary artery.

Part 3 of 3: colorize and name the parts of the heart

Draw the Internal Structure of the Heart Step 12

Step 1. Add pink color

Color in pink:

  • outline,
  • the left atrium,
  • the right atrium,
  • pulmonary veins.
Draw the Internal Structure of the Heart Step 13

Step 2. Bring some purple

Change to purple:

  • pulmonary artery,
  • the left ventricle,
  • the right ventricle.
Draw the Internal Structure of the Heart Step 14

Step 3. Complete with blue

Color in blue:

  • the superior vena cava,
  • the inferior vena cava.
Draw the Internal Structure of the Heart Step 15

Step 4. Finish with the color red

Change to red:

the aorta

Draw the Internal Structure of the Heart Step 16

Step 5. Write the names of the parts of the heart below:

  • 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).
Draw the Internal Structure of the Heart Step 17

Step 6. Complete the labeling

Write “The human heart” at the top of your drawing.

Advice

  • Use a gray pencil to make your sketch.
  • Color the different parts of the heart once you have finished your drawing.
