Have a Heart

Your heart pumps 8,000 gallons of blood every day.

A mature heart beats over 100,000 times in 24 hours.

The heart squirts about ½ cup of blood through its valves with every heartbeat.

When you listen to your heart through a stethoscope, the beats you hear are the valves slamming shut.

Between beats, your heart relaxes for about 5 seconds.

Your veins collect blood from all over your body and return it to the heart. The entire trip from the heart to the muscles and back again takes less than one minute.

During an average lifetime, a human heart will beat almost 3 billion times.

Your blood makes 1,000 complete trips around your body every day.

In a lifetime, your heart might pump up to 50 million gallons of blood.

Your blood contains about 250 trillion red blood cells.

A person's resting pulse rate increases with age.

Generally, larger people have a slightly higher pulse rate.

Canaries live longer than elephants.

Your heart is good for over 2 ½ billion beats in a lifetime of 70 years.

In 2001, the life expectancy of the average American was 80 for men and 74.4 for women.
