because pressure in the systemic circulation is much higher than the pressure in the pulmonary circulation, the left ventricle must do more work to pump blood into systemic circulation than the right ventricle must do to pump blood into pulmonary circulation at the beginning of systole, ventricular pressure is very low, and blood flows passively from atrium to ventricle, but pressure increases ...

50-70%-When we start cardiac cycle, the ventricle already has blood in it --> does this so can hit preload in time for next cardiac cycle -End diastolic volume (EDV) --> mitral valve closes (first heart sound) = filling our ventricle but keeping ventricular pressure low --> compliance of tissue-Isovolumetric contraction: signal to depolarize, two closed valves holding blood --> squeezing ...

Mar 18, 2016 · The cardiac cycle refers to the sequence of events that takes place from one heart beat to the next. A full understanding of the cardiac cycle requires thorough examination of atrial systole, atrial diastole, ventricular systole, ventricular diastole, atrial and ventricular volume changes during the cycle, electrical events (depolarization and repolarization) of atria and ventricular myocytes ...
