PATHOLOGY

Detailed explanation-1: -Blood pressure is measured as two numbers: Systolic blood pressure (the first and higher number) measures pressure inside your arteries when the heart beats. Diastolic blood pressure (the second and lower number) measures the pressure inside the artery when the heart rests between beats.

Detailed explanation-2: -Normal blood pressure for most adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80. Elevated blood pressure is defined as a systolic pressure between 120 and 129 with a diastolic pressure of less than 80.

Detailed explanation-3: -Once your systolic reading reaches 130 or higher or your diastolic reading is 80 or higher, you’re considered to have high blood pressure, or hypertension.
