During each heartbeat, approximately 70cm³ is pushed from the heart at an average pressure of 105mm-Hg. Calculate the power output of the heart, in watts, assuming 70 beats per minute.
*please explain this as simply as possible- thanks so much :)
Volume of blood pumped in one heart beat = 70 cc = 70*10^-6 m^3
