About The Heart

In simple terms, the heart is a pump which keeps blood moving around the body.

This process is crucial as blood delivers oxygen and nutrients to all parts of the body, and carries away unwanted carbon dioxide and waste products.

Although the process may seem straightforward, the heart is an amazing and complex organ.

Some amazing heart facts:

  • The adult heart pumps about 10 pints of blood each minute – approximately 2,000 gallons of blood each day – throughout the body.
  • The system of blood vessels – arteries, veins and capillaries – is over 60,000 miles long. That’s long enough to go around the world more than twice.
  • When attempting to locate their heart, most people place their hand on their left chest. Actually, the heart is located in the center of the chest between the lungs. The bottom of the heart is tipped to the left, so you feel more of the heart on the left side of the chest.
  • The heart beats about 100,000 times each day.
  • In a 70-year lifetime, the average human heart beats more than 2.5 billion times.
  • An adult woman’s heart weighs about 8 ounces, a man’s about 10 ounces
  • A child’s heart is about the size of a clenched fist; an adult’s heart is about the size of two fists.
  • Blood is about 78 percent water.
  • Blood takes about 20 seconds to circulate throughout the entire vascular system.
  • The structure of the heart was first described in 1706, by Raymond de Viessens, a French anatomy professor.
  • The electrocardiograph (ECG) was invented in 1902 by Dutch physiologist Willem Einthoven. This test is still used to evaluate the heart’s rate and rhythm.
  • The first heart specialists emerged after World War I.
