Difference Between Systolic and Diastolic Blood Pressure

Blood Pressure

Blood pressure is a serious health problem which affects nearly 40 to 50 per cent of the total population.

Blood is a fluid connective tissue which is carried to all parts of our body with the help of arteries. It plays a key factor in providing blood (thus oxygen and energy) to organs.

Blood pressure is the force of blood against the arteries. An individual should maintain a normal blood pressure from 90 – 120 / 60 – 80 mm Hg. Blood pressure is given by two numbers, with one above or before the other – 120/80.120 – This is called systolic pressure and 80 – This is called diastolic pressure.
