What is meant by 'systolic pressure' and 'diastolic pressure'? What are their normal values?
Systolic pressure: The pressure of blood inside the artery during ventricular systole (contraction) is called systolic pressure.
Diastolic pressure: The pressure of blood inside the artery during ventricular diastole (relaxation) is called diastolic pressure.
The normal value of systolic pressure is about 120 mm of Hg and the value of diastolic pressure is 80 mm of Hg.
