Your heart beats about 160 times a minute
when you are a baby, 100-120 times a minute when you are a child,
and about 60-90 times when you are an adult.
Your heart is about the size of your
fist.
Blood is circulated around the body every 45 seconds.
If the blood vessels were put end to
end, they would circle the world twice!
The heart beats about 37 million times
a year and pumps some 5,000 gallons of blood in 24 hours.
In a lifetime it has been calculated that the heart pumps enough
blood to fill the Albert Hall!
