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.
