Age-dependencies in the process of enteric absorption

Founded upon experimental and theoretical investigation at age-dependence of the absorping system in human beings is analysed. Starting from a compartment model the absorption, velocity of absorption and effectivity of absorption are defined in the physical sense. The experimental investigations results in a general decrease of the velocity of all the processes in the absorping system with increasing age. This is the reason for a temporal changed kinetic behaviour of aged systems. By comparison between young and aged systems with reference to their kinetic properties we find the following results: With increasing age we observe a decrease of the velocity of absorption and of the effectivity of absorption, but with regard to the quantity of intestinal absorption not a difference between young and aged is pointed out.
