Which one of the following statements is correct regarding blood...

Hypertension is the term for blood pressure that is higher than normal $(120 / 80)$. In this measurement, $120 \mathrm{~mm} \mathrm{Hg}$ (millimeter) of mercury pressure) is the systolic, or pumping, pressure and $80 \mathrm{~mm} \mathrm{Hg}$ is the diastolic, or resting pressure. If repeated checks of blood pressure $190 / 100 \mathrm{~mm} \mathrm{Hg}$ ) of an individual is $140 / 90$ (140 over 90) or higher, it shows hypertension. High blood pressure leads to heart diseases and also affects vital organs like brain and kidney.
