Question

What is meant by 'systolic pressure' and 'diastolic pressure'? What are their normal values?

Answer 1

Systolic pressure is the pressure at which the blood leaves the heart through the aorta, during contraction phase.
Diastolic pressure is the minimum pressure in the arteries during the relaxation phase of the heart.

The normal systolic pressure is 120 mm Hg, while the normal diastolic pressure is 80 mm Hg. These values are written as 120/80.
