P.44 Assume the following simplified dependence of the pressure in a ventricle of the human heart as a function of the volume of blood pumped. Pressure S Pd 0 75 V/cm³ 150 Ps, the systolic pressure, is 120. mm Hg, corresponding to 0.158 atm. Pa, the diastolic pressure, is 80.0 mm Hg, corre- sponding to 0.105 atm. If the volume of blood pumped in one heartbeat is 75.0 cm³, calculate the work done in a heartbeat.
