Blood pressure is a serious health problem which affects nearly 40 to 50 percent of the total population.
Blood is a fluid connective tissue which is carried to all parts of our body with the help of the blood vessels called 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 120 – 140 / 70 – 90 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.
Types of blood pressure
- Systolic Blood Pressure.
The normal range of systolic blood pressure should be 90 – 120 mm Hg.
- Diastolic Blood Pressure.
The normal range of diastolic blood pressure should be 60 – 80 mm Hg.
Both Diastolic and Systolic are derived from the Greek word. Diastolic meaning drawing apart and Systolic meaning a drawing together.
Here is the differenced between systolic and diastolic blood pressure.
|Types||Diastolic blood pressure||Systolic blood pressure|
|Definition||The pressure which is exerted on the walls of the arteries.||The amount of pressure exerts on the arteries and blood vessels.|
|Average Range||In infants–65 mm Hg. In adults– 60-80 mmHg. Age 6 – 9 — 65 mmHg.||In infants -95mmHg. In adults- 90-120 mmHg. Age 6 – 9 –100 mmHg.|
|Ventricles of the Heart||Fill with blood||Left ventricles contract|
|Reading of Blood Pressure||The lower number is diastolic pressure.||The higher number is systolic pressure.|
|Blood Pressure||Diastolic constitutes the minimum pressure in the arteries.||Systolic constitutes the maximum pressure applied to the arteries.|
