The heart pumps
blood through the arteries to various parts of
the body.
A certain amount
of pressure is required to maintain the blood
flow .
Blood pressure is
the force your blood exerts on your arteries as it flows through your body.
When this
pressure increases over the normal level, it is called
high blood
pressure.
If you have high
blood pressure and cholesterol it means that your blood is exerting too much
force on your arteries and is making your heart's job--pumping blood--more
difficult than it should be.
