Vascular Total Peripheral Resistance

1) If total peripheral resistance (TPR) decreases ----- venous return decreases...because of decrease in preload (peripheral pooling of blood)....for example as in case of venodilators which decrease TPR & causing blood to pool in peripheral vessels, thereby decreasing venous return .

2) If TPR decreases -----venous return increases ..because more blood enters arterial system from the venous side ...( as in cardiac vascular function curve). It seems contradictory & is confusing me ...can anyone please explain it ...
