How to Draw a Human Heart
Draw a half-circle or bump that extends from the top left corner of the heart for the right atrium. Sketch the tubular pulmonary artery going under and over the aorta. If you’re drawing a cartoon-style human heart, go around the outline of each segment with a large black pen or marker.
Use charcoal or a pencil to shade or cross-hatch the heart. If you’re learning about how blood circulates through the body and the heart, draw tiny arrows within the heart’s segments. The size of each heart varies from person to person, but an average measurement is the size of a fist.

What is the structure of the heart?
The heart is divided into four chambers: two atria and two ventricles; the atria receive blood, while the ventricles pump it. The right atrium receives blood from the superior and inferior vena cavas, as well as the coronary sinus; blood then moves to the right ventricle, which pumps it to the lungs.
