Cardiac Output - correct answer The amount of blood the heart pumps through the circulatory system in a minute. The amount of blood put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume and the heart rate determine this. - typically about 5L/min at rest - will be higher if physically fit (max of 40L/min) - for unfit, 14-20L/min max Stroke Volume - correct answer Refers to the volume of blood that is pumped by the heart with each...
