    diastolic pressure
    the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood
    arterial pressure
    the pressure of the circulating blood on the arteries
    venous pressure
    the pressure exerted on the walls of the veins by the circulating blood
