Why does the heart have a thick and thin side?

The thick side of the heart is full of muscle. The thick side of the heart is also the side with all of the arteries. It needs all of this muscle to pump blood all around the body through the arteries. The arteries pump oxegynated blood away from the heart. 

Random fact: 

Oxegynated blood is red and de-oxegynated blood is blue. oxegynated blood goes away from the heart through the arteries and de-oxegynated blood comes back to the heart through the veins.
