Why Blood Pressure Rises?

What causes blood pressure to rise? As an illustration, if you're watering the garden with a hose. If you press the end of the hose, the water that comes out will be faster. That's because water pressure increases when the hose is pressed. Also, if you zoom in tap water, the flow of water through the hose will be faster because of increased water discharge.

The same thing happens with your blood. If your blood vessels constrict, the blood pressure in the blood vessels will increase. In addition, if the amount of blood flow increases, blood pressure will also increase.
