Define stroke volume and cardiac output
WebJun 3, 2024 · Stroke volume: The amount of blood pumped by the left ventricle of the heart in one contraction. The stroke volume is not all the blood contained in the left ventricle; … WebSolution. Stroke volume is the volume of blood pumped out of the heart by the ventricles with each heartbeat. Cardiac output is the volume of blood pumped out of the heart by the ventricles per minute. Hence, stroke volume is equal to 60 to 70 ml of blood/heartbeat and cardiac output is equal to 3 to 5 liters of blood per minute.
