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.
Health and blood pressure
The incidence of hypertension increases with age. In addition, a lack of
exercise, excess body fat and high levels of cholesterol (LDL), which sticks to
the inside in blood vessels, reduces elasticity of these vessels.
