Chapter 2 Important information about blood pressure and its
measurement
2.1 How does high blood pressure arise?
Blood pressure and heart rate are controlled by the lower portion of the
brainstem called medulla oblongata. Blood pressure is dynamic and responds to
respective situation by way of feedback mechanism via the nervous system. To
adjust for blood pressure, the strength and frequency of the heart (pulse), as well
as the width of circulatory blood vessels respond by changing. The latter is
affected by way of fine muscles in the blood vessel walls. The level of arterial
blood pressure changes periodically during the heart activity: During blood
ejection (Systole), the value is maximal (systolic blood pressure value); at the end
