Physiology of Aging Aging is a normal process in which the rate of catabolic changes become greater than the rate of anabolic cell regeneration. Aging is a normal process in which the rate of catabolic changes become greater than the rate of anabolic cell regeneration. Loss of cells and body mass can lead to varying degree of decreased efficiency and impaired organ function.
