Isovolumetric contraction is that stage when the ventricles continue to contract even though the blood volume stays the same. How and when exactly do this happen?
Here, Leslie discusses how stroke volume can be regulated. Depending on which factors are changed, blood volume entering the heart may increase and in effect increasing heart contraction too. Watch, listen, and learn how this happens.
Stroke Volume = EDV – ESV What do these mean? Watch to learn more and understand about stroke volume.
