What cause bp?

Multiple factors: The heart pumps blood under pressure into the arteries. The higher the resistance to flow the higher the pressure. Thus both the pressure generated by the heart and the resistance from the arteries determine the pressure. Hormones, kidney function, blood volume (salt related), the autonomic nervous system, etc. All regulate this process and can be responsible for abnormalities of blood pressure.

BP definition.: The blood pressure is the resistance to blood flow through the body. The higher number is the resistance when the heart pumps, and the lower number is the resistance when the heart relaxes and fills. High BP can lead to problems with the heart, kidneys, eyes, blood vessels and brain. 95% of the time, there's no one specific cause perhaps other than genetics.
