* The amount of force with which the blood pumps
* The amount of blood in the body
* The blood vessel's diameter
So that generally, blood pressure rises when the heart pumps harder, there is an increase in the amount of blood in the body, or there is a decrease in the diameter of the blood vessels that carries the blood.
Importance
Adequate blood pressure is vital to those organs and tissues that depend on the nutrients and oxygen that the blood supplies to keep them healthy. Without the proper pressure, waste materials would damage cells that depend on venous blood to carry it away to be discarded. For this crucial exchange of nutrients and waste to occur, pressure and concentration must be maintained within certain levels. …show more content…
Contrary to how it sounds, it has nothing to do with being tense or hyperactive; it is a condition where the blood is flowing through the vessels at too great a pressure to ensure the health of the vessel over the long term. Any pressure that is 140 over 90 or higher is considered too high and unhealthy. This level will damage vessel walls over time, leading to very serious health issues.

Secondary Hypertension is high blood pressure, which is caused by a disease, however most people who suffer from high blood pressure, suffer from essential or primary hypertension. The exact cause of this is unknown although the theories involve several mechanisms. Risk factors include:
