What increases venous return?
According to Starling's law, an increase in venous return (i.e. increase in preload on the ventricles) results in a more effective contraction, hence augmenting cardiac output, as long as the actin and myosin fibrils in the muscle fibers are not overstretched. In the most simple terms, the more blood the heart collects blood from venous return, the more it is able to distribute through cardiac output. If venous return is poor, cardiac output will be poor- basically like a water pump that is connected to an insufficient supply of water.
