The human heart puts in a lot of work to keep the body up and running. In fact, the heart beats approximately 100,000 times every day and 35 million times each year. It's made out of special muscles that allow it to continuously pump blood over the course of a lifetime with no working out required. The heart is so strong that it could theoretically squirt blood thirty feet across a room, equivalent to over 4 pounds of force per square inch.
