for a moment a full balloon attached to a tire. The air inside the tire is under pressure,
it’s trying to get out and pressing against the walls of the tire. Is someone comes along
and squeezes to air from the balloon into the tire, the air pressure inside the tire goes

That tire is the body’s blood vessels – the arteries and veins. They are constantly
under pressure from all the blood they carry. The balloon is the heart. When it is
resting it is full of blood, but when it beats it squeezes and all that blood goes into the
blood vessels, raising the blood pressure.

This why a blood pressure reading has two numbers, the higher number is for when
the heart is beating and the lower number is for when it is resting.

If the blood pressure is too high, it damages the blood vessels, the same way a tire
under too much air pressure might burst. With high blood pressure, there are a number
