Heart facts

he

Your 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!

The adult heart pumps about 5
quarts of blood each minute –
approximately 2,000 gallons of
blood each day – throughout the
body.

When attempting to locate their
heart, most people place their
hand on their left chest.

Actually,
your heart is located in the center
of your chest between your lungs.

The bottom of the heart is tipped
to the left, so you feel more of
your heart on your left side of
your 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.
