Are you fascinated with anatomy, or looking to take your drawing skills to the next level? Drawing realistic anatomy can be a challenge. To draw the internal structure of a human heart, follow the steps below.
Steps
-
![Step 1 To find a good diagram, go to Google Images, and type in "The Internal Structure of the Human Heart".]()
To find a good diagram, go to Google Images, and type in "The Internal Structure of the Human Heart". Find an image that displays the entire heart, and click on it to enlarge it.[1] -
![Step 2 Find a piece of paper and something to draw with.]()
Find a piece of paper and something to draw with. Start with the pulmonary veins. They will be to the lower left of the Aorta. There are two of them. Draw the top vein slightly smaller than the bottom vein.Advertisement -
![Step 3 Below the pulmonary veins, and slightly to the right, begin sketching the bottom of the inferior vena cava.]()
Below the pulmonary veins, and slightly to the right, begin sketching the bottom of the inferior vena cava. -
![Step 4 Begin sketching the base of the heart, including the right and left ventricles, and the right and left atriums.]()
Begin sketching the base of the heart, including the right and left ventricles, and the right and left atriums. 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.[2] -
![Step 5 Change diagrams if needed.]()
Change diagrams if needed. If the diagram that you are using is helping you to sketch the heart, you should continue to use the same diagram. If you are confused about where parts of the heart are, find a new diagram.
-
![Step 1 Draw the other side of the pulmonary veins, and add circles at the end.]()
Draw the other side of the pulmonary veins, and add circles at the end. -
![Step 2 Begin drawing the pulmonary artery.]()
Begin drawing the pulmonary artery. Bottom ends at the top of the right ventricle. The left and right sides should be slightly above the atriums and pulmonary veins. The pulmonary artery is shaped like an uppercase 't'. It extends to the top of the right ventricle. Draw a circle at the end of it at the bottom.[3] -
![Step 3 To draw the aorta, begin by drawing the loop over and around the pulmonary artery, ending at the top of the left ventricle.]()
To draw the aorta, begin by drawing the loop over and around the pulmonary artery, ending at the top of the left ventricle. To draw the back of the aorta, draw a single line connecting from the right side of the pulmonary artery to the top of the left atrium. To finish drawing the aorta, draw three nubs at the top of the loop. After you draw these, erase the lines connecting from one side of the bottom of the nub to the other. Add tilted circles to the top of all of the nubs. Draw a circle at the bottom of the aorta, adjacent to the left ventricle. -
![Step 4 To draw the...]()
To draw the superior vena cava, draw a nub extending from the top of the right atrium, overlapping the left side of the pulmonary artery, to slightly above the left side of the pulmonary artery. At the bottom of the superior vena cava, adjacent to the right atrium, draw a circle. -
![Step 5 Draw four circles in the left atrium, and one circle in the right atrium, slightly below the superior vena cava.]()
Draw four circles in the left atrium, and one circle in the right atrium, slightly below the superior vena cava. -
![Step 6 Draw the mitral valves between both atriums, and aortic valves in both the pulmonary artery and the aorta.]()
Draw the mitral valves between both atriums, and aortic valves in both the pulmonary artery and the aorta.

QuestionHow big is the human heart?
Community AnswerThe human heart is roughly the size of a large fist. The human heart weighs about 10 to 12 ounces in men, and about 8 to 10 ounces in women. -
QuestionHow do I draw heart muscles?
Read4everCommunity AnswerThe muscles are drawn as thick lines in the cross-section and the outside is completely made out of muscles. There is no need to specifically draw muscles, as they are already incorporated in the diagram. -
QuestionHow many hearts does an octopus have?
CraftsmartTop AnswererAn octopus has three hearts. One heart is to circulate the blood around the body, while the other two are for pumping the blood to the gills.

Tips
-
Use pencilThanks
-
Do not start coloring until you have drawn the entire diagramThanks
Tips from our Readers 
- Try placing an extra sheet of paper or a cloth under your drawing hand on top of your drawing so sweat won't smudge the ink.
Warnings
- If you do not use pencil, you may have to start over if a mistake is made.Thanks

About This Article
To draw the internal structure of the heart, start by sketching the 2 pulmonary veins to the lower left of the aorta and the bottom of the inferior vena cava slightly to the right of that. Then, fill in the base of the heart with the right and left ventricles and the right and left atriums. Once you have the basic outline of the heart sketched out, use an existing diagram to help you fill in the additional veins and muscles, like the mitral and aortic valves. After you’ve drawn the structure, color the different sections of the heart distinct colors and appropriately label them. Make sure to write “The Human Heart” above your drawing as a title when you’re finished. For more help, like including how to give your drawing more details, read on.
