Biphasic disappearance of injected substance from plasma. During the first phase, equilibration of the injected substance takes place between the intravascular and extravascular compartments (k2). Once equilibration has been reached, the decline in plasma levels (normally measured with a venous sample) should reflect removal of the substance from the arterial system through the kidneys. This is termed the terminal elimination phase (k1)
