Your heart is located in the upper left-hand side of your chest and if you place your hand there, you can feel it beating. The heart continually pumps blood to all parts of the body, and never stops beating, even when you are asleep. Because of its importance, many complex surgeries (and even artificial hearts) have been developed to keep your heart going thump, thump, thump.
