There are many fun facts about the heart that children can understand, including that an average female heartbeat is nearly eight beats faster per minute than the average male heartbeat, explains Cleveland Clinic. A person's risk of heart disease lowers as he acquires more education, and heart disease can be traced as far back as 3,000-year-old mummies. Christmas Day brings the largest number of heart attacks, with December 26 and New Year's Day closely behind.
A human heart is approximately the same size as two small hands clasped together, while the average heart valve is nearly the size of a half dollar, states Cleveland Clinic. The blue whale boasts the largest heart of all animals, weighing more than 1,500 pounds.
The human heart beats 100,000 times a day, and it pumps 1.5 gallons of blood every minute, says the Cleveland Clinic. The beating sound of a heart stems from the flutter of valve leaflets opening and closing. The right side of the heart pumps blood into a person's lungs, while the left side circulates the blood throughout the body.
Prior to the invention of the stethoscope, doctors had to press their ear directly against a person's chest in order to hear a heartbeat, explains Cleveland Clinic. Out of modesty, the stethoscope was invented.
