x8 The heart pumps blood to almost all of the body’s 75 trillion cells, only bypassing the corneas. The average adult heart beats 72 times a minute, 100,000 times a day, and 2.5 billion times over the course of a lifetime. Squeeze a tennis ball. That’s how hard a beating heart works to pump blood. Each minute, the heart pumps between 5 and 30 liters – or up to 8 gallons – of blood. A woman dies from heart disease almost every minute, making it the #1 killer of women. One in 3 American women die of heart disease each year. Couples who are in love synchronize their heart rates after gazing into each others’ eyes for three minutes. + 199 Your heartbeat changes and mimics the music you listen to. Your heart will pump enough barrels of blood during your lifetime to fill more than three super tankers or 200 train tank cars. SOURCES Avraham, Regina. The Circulatory System. Philadelphia, PA: Chelsea House Publishers, 2000. Daniels, Patricia, et. al. Body: The Complete Human. Washington, D.C.: National Geographic Society, 2007. Every day, your heart creates enough energy to drive a truck for 20 miles. Over your average lifetime, it’s enough to drive to the moon and back. Historical fact: CT scans of mummies reveal that heart disease was frequent in ancient Egypt, showing that unhealthy modern lifestyles aren’t the only cause of heart disease. The heart can continue to beat even when separated from the body because it has its own electrical impulse. All it needs is an adequate supply of oxygen.
