Miquel Química non non Aging process Aging process dynamical systems Aging process was considered from the thermodynamic point of view. This approach is based on the non linear theory of dynamic systems which permits to study the bio-systems beyond the classical scope and on dissipative structures. Several oscillating and chaotic chemical systems were studied using the rate of entropy production as an extension of the thermodynamics of irreversible processes to chemical systems far from the equilibrium. Calculations of rates of entropy production in human beings have confirmed the hypothesis that stable evolution of bio-systems may occur through a chaotic dynamic state. Thus, periodic or quasiperiodic oscillations may emerge as a natural way and then can be postulated that aging process begins. The system becomes more sensitive to perturbations, increasing the damages and leading to degenerative diseases. 2003 artículo científico 1015-8553 https://www.redalyc.org/articulo.oa?id=181626024006 en http://www.redalyc.org/revista.oa?id=1816 Revista CENIC.
