what is blood pressure?
In: Biology
It is the amount of force your blood exerts against the walls of your blood vessels when your heart is pumping, as well as the amount of force exerted between those heartbeats. That’s why there are two numbers. The higher number is when the heart beats, pumping your blood through. The lower number is the force exerted against your blood vessels between pumps. High blood pressure can be a sign of arterial sclerosis as well as a precursor to heart disease and stroke.
