Blood pressure represents the pressure of the blood in the major arteries of the body.
This blood pressure increases in the arteries when the ventricle contracts to push the blood to the major artery by a mechanism called ventricular systole. This increased blood pressure number is known as systolic blood pressure which is usually 180 mm of Hg.
