WebbThe Frank-Starling mechanism is a physiological principle that explains how the heart responds to changes in venous return. Increases in venous return cause the heart's chambers to fill with more blood, which then causes the heart to stretch and contract more forcefully, and pump more blood out to the rest of the body.
