Cardiac output is the amount of blood the ventricles pump out in 1 minute; normally, 4 to 6 L/minute. Blood pressure is the force exerted by the blood against the walls of the blood vessels. Systolic blood pressure, in this example 120, is the force during ventricular contraction. Diastolic blood pressure, in this example is 80, is the force during ventricular relaxation. The difference between systolic and diastolic pressure is called pulse pressure.
