Blood pressure is the force or pressure that blood puts on the walls of your arteries as it goes through your body. Blood Pressure readings are usually written as 2 numbers. The first and higher number is called systolic pressure. It is the pressure in your blood vessels when your heart beats. The second and lower number is called the diastolic pressure. It is the pressure in your blood vessels when your heart is resting between beats.

Blood pressure is the pressure of what the blood exerts on the walls of the blood vessels. The pressure, that the blood exerts on the wall of the blood vessel, depends on the the heart. When the heart (ventricles) contract, the blood is forced out and into the arteries. Since the blood it forced, the pressure is high. That gives you the higher reading, and it is called SYSTOLE. When the heart relaxes between contractions, blood is not forced into the artieries. But, the elastic walls of the arteries - which were streched by the force of the contraction before -, recoils, applying the pressure to the blood. That way the the blood keep flowing. Since this pressure is less then the pressure what the contraction gives, the reading will be lower. That lower reading is called DIASTOLE.
The lowest pressure exerted by blood in your arteries is your diastolic blood pressure.
