General information about blood pressure

Blood circulation
The blood circulation is responsible for supplying
the body with oxygen. Blood pressure is the
pressure exerted on the arteries.
The systolic blood pressure value (higher pressure
or top value) represents the blood pressure
produced by contraction of the heart muscle.
The diastolic blood pressure value (lower pressure
or lower value) represents the blood pressure
produced by relaxation of the heart muscle.
Classification of blood pressure
The World Health Organisation (WHO) and the
International Society of Hypertension (ISH)
developed the blood pressure classification. This
classification is based on the blood pressure values
measured while sitting on a chair in the outpatient
department of a hospital.
