Question

Explain the Term
Blood Pressure

Answer 1

When the blood flows in the artery it exerts pressure on the elastic wall of the artery which is called blood pressure. It is greater during systole (contraction) than during diastole (relaxation) of the heart. In a normal adult, the blood pressure is 120/80 where systolic is 120 and diastolic pressure is 80 mm of Hg (mercury).
