A FEW WORDS ABOUT BLOOD PRESSURE
Blood pressure is the force exerted
on the walls of your blood vessels
as blood flows through them.
Your heart is like a pump.When it
contracts, or beats, it sends a surge
of blood through the blood vessels
and pressure increases.This is
called your systolic pressure.
When your heart relaxes
between beats, your blood pressure
decreases.This is called your
diastolic pressure.
When a doctor takes your blood
pressure, he or she measures both
our systolic and diastolic presssures
and records them as numbers.For
xample, if your blood pressure
reading is 126/76 (126 over 76),
our systolic is 126 and your diastolic
is 76.The numbers are calculated
in millimeters of mercury and
recorded as 126/76 mm Hg.
