Knowing Some Fundamental Aspects of High Blood Pressure
From medical perspectives, our arteries are naturally designed to work very well under pressure. Although we cannot see or even feel them in our body at every given moment, however, both our heart and blood vessels are involved in the complex rhythm pressure and resistance. Blood pressure, by definition, is actually the amount of force exerted by the blood inside of our arteries when our blood is being pumped throughout the circulatory system. So, every time our heart muscle is functioning, the blood in our body is being pressed against the walls of vessels around as it is calculated and viewed as part of our systolic blood pressure. So, by the time when our heart begins to relax itself between pulses, the pressure on those walls occurred are calculated as part of the diastolic blood pressure.

Generally, our blood pressure never goes constantly steady at any moment. Perhaps, this is because our body is constantly adjusting to the demands of blood supplied at a certain period. In fact, our blood pressure can change drastically in a matter of seconds. For example, running quickly towards the elevator, hearing the sound of broken glass, or having terrible confrontation with someone else can literally increase our blood pressure surged from 130 mm/Hg to 160 mm/Hg or even more.

There is no doubt that even if we have measured our blood pressure repeatedly, we may end up visiting our doctor again. When a doctor’s meter cuffed or tightened on our upper arm and placing a stethoscope on our elbows, whether we are being conscious or not, he is actually "peeking" into our blood circulatory system inside our main artery system around our arm. 

Technically, when a doctor’s meter is tightened on our arm as he is peeking into our blood circulatory system, the first thing that he will hear is the sound of our blood flowing back into our artery which is being pressed, and taking a note from any numbers appeared on the meter in order to determine the rate of our systolic blood pressure. Additionally, any numbers appeared on the doctor’s meter at the very last moment along with the sounds of our beats will indicate the rate of our diastolic blood pressure.

Meanwhile, when a person’s heart has to work overtime, his or her heart muscle becomes larger and the arteries are pounding relentlessly against the walls (blood vessels). When this happens, it makes the arteries become stiff and narrow. So, when our arteries become stiff and narrow, this will eventually cause such a potential risk of harmful disease like stroke, kidney failure, and heart attack. Overall, there are many modern tools produced nowadays which are designed to help us in monitoring our blood pressure conveniently.
