  91. 91. Why We Need Blood Pressure? <ul><li>Blood pressure is needed to push the blood along the blood vessels to reach the various tissues of the body </li></ul>
  92. 92. Essential Hypertension <ul><li>In Primary or Essential Hypertension both the systolic as well as diastolic blood pressures are elevated to almost an equal extend </li></ul>
