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

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.

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.
