Are you passionate about anatomy or just want to take your own drawing skills to the next level? It can be challenging to depict a person's internal organs realistically. To draw the internal structure of the human heart, follow the step-by-step guidelines in this article.

Steps

Part 1 of 3: Find a finished heart shape and create an initial sketch

  1. 1 Find a quality image of the structure of the heart. To find a quality image, go to Google Images and enter the following phrase into the search box: "The internal structure of the human heart" (without quotes).Find the image in which the heart is presented in full and click on it to enlarge.
  2. 2 Find a piece of paper and the inventory with which you will draw. Begin by sketching the outlines of the pulmonary veins. They are located below and to the left of the aorta. There are two pulmonary veins in the heart. Draw the lower vein slightly larger than the upper one.
  3. 3 Having marked the outlines of the pulmonary veins, below and slightly to the right of them, begin to draw the outlines of the inferior vena cava.
  4. 4 Start outlining the outer contours of the heart itself, including the right and left ventricles, as well as the right and left atria. The pulmonary veins should be adjacent to the right atrium, and the inferior vena cava should be adjacent to the right atrium and right ventricle.
  5. 5 If necessary, use different images of the heart, which you take as the basis of your drawing. If the image you are already sketching is enough for you, then just continue to use it. If you are confused by some of the details of the image used, find additional, more understandable pictures to help you.

Part 2 of 3: Draw the heart

  1. 1 Draw the other ends of the pulmonary veins on the right and indicate their circular cross-section.
  2. 2 Start drawing the pulmonary artery. Its lower end (pulmonary trunk) should be at the top of the right ventricle. The left and right branch of the pulmonary artery should be located just above the atria and pulmonary veins. The pulmonary artery is T-shaped. And it leaves directly from the upper part of the right ventricle of the heart. Draw a circular section of the artery at the bottom of the pulmonary trunk.
  3. 3 To draw the aorta, start by drawing a loop above and around the pulmonary artery (its right branch), ending at the top of the left ventricle. To draw the second side of the aorta, draw another line from the right wall of the pulmonary artery to the top of the left atrium. To complete the contours of the aorta, draw three arteries branching from the aorta from above. Then erase the extra lines at the base of the branches. Add oval sections at the top of the three branching arteries. Draw a circular cross-section at the lower end of the aorta at the left ventricle of the heart.
  4. 4 To display the superior vena cava, draw a branch from the top of the right atrium, covering the left pulmonary artery and protruding just above it. At the bottom of the superior vena cava, draw a circular section at the right atrium.
  5. 5 To indicate the holes, draw four circles in the left atrium and another circle in the right atrium just below the superior vena cava.
  6. 6 Draw mitral valves between both atria, as well as the aortic valves in the pulmonary artery and aorta.

Part 3 of 3: Color in the drawing and add captions

  1. 1 Color the following elements of the picture in pink:
    • borders;
    • left atrium;
    • right atrium;
    • pulmonary veins.
  2. 2 Color in purple:
    • pulmonary artery;
    • left ventricle;
    • right ventricle.
  3. 3 Color in blue:
    • superior vena cava;
    • inferior vena cava.
  4. 4 Color in red:
    • aorta.
  5. 5 Be sure to sign the following heart elements on the picture:
    • 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).
  6. 6 To finish the work, sign the name of the picture at the top:"The structure of the human heart".

Tips

  • Draw with a pencil.
  • Do not start coloring the drawing until you have completed it completely.

Warnings

  • It is better to work with a simple pencil - otherwise, if you accidentally make a mistake, you will have to start all over again.
