Human blood pressure basics

Blood pressure is the pressure of circulating blood on the walls of blood vessels. Most of this pressure is due to work done by the heart by pumping blood through the circulatory system. Used without further specification, "blood pressure" usually refers to the pressure in large arteries of the systemic circulation.

Pressure?

5. Normal resting blood
pressure, in an adult is
approximately 120
millimetres of mercury
(16 kPa) systolic, and 80
millimetres of mercury
(11 kPa) diastolic,
abbreviated
"120/80 mmHg".

6. There are two types of blood pressure:


Systolic blood pressure refers to
the pressure inside your arteries when your
heart is pumping

Diastolic pressure is the pressure inside your
arteries when your heart is resting between
beats.

8. In a blood pressure
reading, the systolic
number always comes first,
and then the diastolic
number. For example, your
numbers may be "120 over
80" or written as 120/80.

9. It is an instrument for measuring
blood pressure, typically consisting
of an inflatable rubber cuff which is
applied to the arm and connected
to a column of mercury next to a
graduated scale, enabling the
determination of systolic and
diastolic blood pressure by
increasing and gradually releasing
the pressure in the cuff.
