Line 1: Line 1:
 +The amount of blood per minute pumped out by each of the two ventricles of the heart. A typical value in an adult at rest is 5 litres per minute. The output of each ventricle is the product of the stroke volume (about 70 ml) and the heart rate (about 70 per minute). The output increases with muscular activity, in work or exercise perhaps to a maximum of 4-5 times the resting rate in an average healthy person, or up to 6-7 times in athletes; heart rate increases by a greater factor than stroke volume.
