The heart is a muscular pump The heart is a muscular pump. When it beats it pumps blood to the lungs and around the body. The amount of blood pumped can be calculated: Heart Rate x Stroke Volume = Cardiac Output. Heart rate: The number of heart beats per minute. Stroke volume: The volume of blood pumped from heart with each beat. Cardiac output: The amount of blood pumped by heart in one minute.
