ABOUT “BLOOD PRESSURE”
What is blood pressure?
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.
Your blood pressure changes all the time.
Your blood pressure differs according to your age, gender and a range of other
factors. It is likely to be affected by your biorhythm during the day and by your
posture, physical activities, mental activities, level of stress and even by the air
temperature. The blood pressure of a healthy person generally varies within a day.
