In An Organism There Are Very Deep Shifts
In an organism there are very deep shifts - there are the signs peculiar to a diabetes and an atherosclerosis, stability to an infection decreases. At last gorbushi-females postpone caviar, which man's individuals of humpback salmons. In one-two weeks fishes-parents perish. A cause of death are plural heart attacks of heart, a brain, lungs, kidneys. It is clear, as concentration of cholesterol in blood at in spawning increases to 1000 mg of %, that is approximately in 10 times. The �destruction mechanism is a typical example of death from the internal reasons, and the example making impression about existence of programmed death. The life of fish as though terminates according to the program stored in genes, - as if in them the signal of "feet" which sharply breaks a life is written down. The description of natural death is very often used as an example characterising presence of the genetic program of ageing and death. Whether but so it? To really, each kind the certain limit of longevity, hence, genetic, that is "written down" in genes, a limit.

But At The System Approach To The Ageing
But at the system approach to the ageing phenomenon value gets that helps to find a generality in various and unity in all. However the general principles of cybernetics cannot by simple extrapolation on an ageing problem explain its mechanisms. The cybernetics helps to understand, how the system works, but it cannot in itself, out of the concrete data and without the aid of concrete ideas to explain why in the course of normal ageing of system of regulation cease to carry out the dominant role. And moreover, why action of cybernetic control systems forms that we name normal ageing. In this last phrase the special sense which will open to the reader in process of acquaintance with the materials presented in the book is concluded. If to tell briefly normal ageing does not exist in itself as function of astronomical time, and is a consequence of work of an organism which, operating on cybernetic principles, carries out the program of development of an organism, and then transforms this program to the ageing mechanism.
It Is Natural That At The Heart Of
It is natural that at the heart of adaptation power processes also lie. At last, ability to reproduction is that property of live system which provides kind preservation. Reproduction process also is supported by power system activity. The extreme variant of such support shows an example concerning the mechanism of natural �destruction . Three basic properties live are in close interaction. But they are united still by the requirement shown by it by development of an organism. The increase in the sizes of a body, strengthening of protective functions and maturing of ability to reproduction visually enough characterise increase in capacity power, adaptable and sexual (reproductive) systems in process of organism development. Three properties live require the structural organisation, that is presence of the certain mechanism which would allow them to be shown in an organism. Accordingly in each difficult organism there are power, adaptable and reproductive systems which can be designated as power, adaptable and reproductive .
