Starling’s law

- the heart pumps all the blood that returns to it without undue damming of blood in the veins.

- (also known as Frank-Starling law of the heart) states that when the diastolic filling of the heart is increased or decreased with a given volume, the volume of blood which is then ejected from the heart increases or decreases by the same amount. That is, more blood in: more blood out.
