WebMay 1, 2003 · Arterial compliance, defined as the ratio of change of volume to change in pressure (or the slope of the pressure volume curve), has been described as a predictable … The terms elastance and compliance are of particular significance in cardiovascular physiology and respiratory physiology. In compliance, an increase in volume occurs in a vessel when the pressure in that vessel is increased. The tendency of the arteries and veins to stretch in response to pressure has a large effect on perfusion and blood pressure. This physically means that blood vessels with a higher compliance deform easier than lower compliance blood vessels under the …
