Sometimes there are fluctuation in the blood pressure or changes in blood pressure are routinely made in order to direct appropriate amounts of oxygen and nutrients to specific parts of the body. For example; during the exercise, the supply of blood increases in the body as it is a good change in the blood pressure.The normal measured values for a resting, healthy adult human is 120 mmHg systolic and 80 mmHg diastolic.

But when there is some kind of barrier in the artery and veins, then they are unable to supply the essential amount of the blood to the body parts which in results causes uneasiness and diseased conditions.
