Draw a Human Heart

Despite the fact it may look complicated, the heart is just a pump, and it's easy to draw.

Steps

First draw the weird cross between a triangle and an oval.
Now add part of a circle behind it on the left.
Add a small tube behind that takes in blood from the body, and next to that draw the beginning of the Aorta. Draw a horizontal line on the right to start the Pulmonary Vein.
Finish of your Aorta and Pulmonary Vein, then add the Pulmonary artery sticking out on both sides.
Now you can shade it in so it looks more realistic. Enjoy your heart!
