ABOUT “BLOOD PRESSURE”

What is blood pressure?				English
The heart is a pump that circulates blood throughout your body. Blood is pumped
from the heart at a constant pressure into arteries. This pressure is called the
arterial blood pressure and represents, in general terms, your blood pressure. Blood
pressure is indicated by several kinds of pressures, including the systolic pressure
that occurs when the heart pumps blood, and the diastolic pressure that occurs
when blood returns to the heart.			Español
