More Pressure-Volume (PV) Curves

The video tutorial explains the cardiac cycle, focusing on the pressure-volume loop of the left ventricle. It covers the phases of ventricular filling, atrial systole, isovolumetric contraction, ventricular ejection, and isovolumetric relaxation. The tutorial also demonstrates how to calculate stroke volume using end diastolic and end systolic volumes. The video aims to clarify the complex interactions of pressure and volume changes in the heart, providing a comprehensive understanding of the cardiac cycle.
