Dec 20, 2017

Blood pressure is the pressure of blood flow that acts on the wall of the blood vessel .It is the motive force to promote the flow of blood in the blood vessels. When the ventricle contracts, blood will flow from the ventricles to the arteries.At this time the blood pressure on the arteries is the highest and is called systolic blood pressure (SBP). During ventricle diastole , arterial elasticity retracts. Blood is still moving slowly, but blood pressure is decreasing. The pressure is called diastolic blood pressure (DBP).
