The heart symbol we all know, while looking nothing like the actual organ, has become synonymous with love and passion across the world. Over five centuries ago the heart symbol we know replaced its predecessor. Before the popularization of the modern day heart symbol the heart was represented with an aorta sticking out from between the curves. With the removal of the aorta, the modern day heart symbol was created. The symbol is associated with Valentines Day, card suits, cupid, and almost everything romantic.
