The human heart is an important part of the circulatory system and its beat is what keeps blood flowing through your body. In fact, National Geographic reports that the human heart pumps approximately two gallons of blood to every area of your body. If the heart is the subject matter of your latest class or science project, you may be required to draw a picture of it. While the heart is indeed an intricate organ, a simple illustration can be drawn to depict its main features.
Begin your heart picture by drawing the main part of the heart with the pulmonary artery erupting from the upper area. It is the pulmonary artery that is responsible for carrying blood from the heart to the lungs.
Add the left ventricle and atrium to your heart picture, followed by the right atrium and ventricle. It is the job of the right side of the heart to collect de-oxygenated blood and pump it into the lungs. The lungs then oxygenate the blood, and it is then pumped back into the heart through the left side.
Draw the vena cava at the upper left of your heart. The vena cava is a very large vein that is responsible for carrying the blood from the upper areas of your body back into the heart.
Add the aorta to the upper part of your heart picture. The aorta is not only one of the most important arteries in the heart, it is also the biggest. It is the job of the aorta to supply oxygenated blood to all of your arteries.
Carefully add the remaining major veins of the heart to your picture. The pulmonary vein is located below the pulmonary artery, and both are oxygenated blood carriers.
Finalize your drawing by adding arrows that denote the direction of blood flow in and out of the heart.
- Drawing pencil
Enhance your drawing by labeling the different parts of the heart.
Sketch your drawing in pencil first, otherwise you will not be able to erase any errors you may make. Later, when it is completed, you can make it bolder by outlining it in marker.
