What exactly is blood pressure? why can it be dangerous?

A doctor has provided 1 answer

Blood pressure: The heart pumps blood through the arteries which then passes thru capillaries into the veins and back to the heart. The flow of blood through the arteries opposed by the resistance of the arteries and runoff produces hemodynamic pressure in systole and diastole. When the resistance is too high it forces the pressure to be too high which causes kidney, vascular and heart problems from the pressure
