The frank-starling mechanism

WebThe Frank-Starling mechanism works by raising the tension produced by cardiac cells when stretched. This increase in tension causes myocardial cells to contract more strongly, increasing the heart's stroke volume. This mechanism is controlled by the autonomic nervous system, which is in charge of heart rate regulation. ... WebThe increased volume of blood stretches the ventricular wall, causing cardiac muscle to contract more forcefully (the so-called Frank–Starling mechanisms). The stroke volume may also increase as a result of greater contractility of the cardiac muscle during exercise, independent of the end-diastolic volume.
