- Interesting Facts about the Human Heart
1) The average adult heart beats 72 times a minute; 100,000 times a day; 3,600,000 times a year; and 2.5 billion times during a lifetime.
2) Though weighing only 11 ounces on average, a healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each day.
3) Because the heart has its own electrical impulse, it can continue to beat even when separated from the body, as long as it has an adequate supply of oxygen.
4) "Atrium” is Latin for “entrance hall,” and “ventricle” is Latin for “little belly.” 5) Grab a tennis ball and squeeze it tightly: that’s how hard the beating heart works to pump blood.
6) In 1903, physiologist Willem Einthoven (1860-1927) invented the electrocardiograph, which measures electric current in the heart.
7) The hearts of a man and woman in love will begin to synchronize after the couple has gazed into each other’s eyes for three minutes.
8) Strong emotions and stress can literally break a person's heart. This condition is called "takotsubo's cardiomyopathy" or "broken heart syndrome." It primarily affects postmenopausal women.
9) French physician Rene Laennec (1781-1826) invented the stethoscope when he felt it was inappropriate to place his ear on his large-buxomed female patients' chests.
10) The “thump-thump” of a heartbeat is the sound made by the four valves of the heart closing.
