Biological Theory of Aging

Biological Theory of Aging Tick tock, tick tock, whats that fail? According to this theory, its your biological clock, ticking away at a preset rate. This theory says that DNA, the cells genetic material, holds the key to your planned demise from day single. objet dart this aging theory appears fatalistic on the surface, remember that biology is not destiny. You cant change your genes, but you can slow the march of epoch with cleanse eating habits and regular exercise. Your body produces hormones that help regulate myriad functions, including issue and behavior, reproduction, and immune function.In your youth, hormone production is high, but as you get older, hormone levels drop off, causing declines in the bodys ability to repair itself and to keep surgical procedure in top form. Working cells produce waste. Over clipping, cells make more waste than they can possibly get rid of, which may solve havoc on their ability to function and slowly lead to their finale . Lipofu scion, or age pigment, is one of the waste products found primarily in some nerve and gist-muscle cells. Lipofuscin binds fat and proteins together in the cells.It accumulates over time and may interfere with cell function. The protein collagen is at the heart of this theory. Collagen, akin to the bodys glue, is one of the about common proteins making up the skin, bones, ligaments, and tendons. When were young, collagen is pliable. But with age, collagen becomes more rigid, and it shrinks. Thats why your skin is little elastic than before (Alston, 2008). Aesthetics aside, cross-linking may pile the transport of nutrients into cells as well as obstruct waste-product removal.Free radicals are devastating marauders roving your body, ready to pounce on healthy cells. They are produced as part of the millions of chemical reactions your body performs to sustain life (Ward, 2012). Your body excessively makes them in response to environmental toxins much(prenominal) as excessive cad ences of naked sunlight and smoking. Free radicals oxidize your cells (think rusting metal). As unbalanced, volatile oxygen molecules, they sacrifice healthy cells to make themselves more stable. Free radicals destroy or alter DNA, the cells genetic blueprint, and disrupt mevery other cell functions.Free radicals may kill cells as a result of their marauding, or they may hit rise to mutant cells that can lead to chronic conditions including cancer and heart disease. Fortunately, the body maintains a sophisticated defense system against free radicals. Unfortunately, our defenses decrease with time, and cell damage ensues (Ward, 2012). This theory could also be called The Use It and stomach It Theory. The idea is that use, and overuse, of your organs pushes them to the brink of destruction.A poor diet, too much alcoholic beverage and cigarette smoking are thought to accelerate natural vesture and tear. With age, the body is less able to repair itself. How does grind and tear d erive? Free radicals, which inflict cellular damage, may be culpable. Similar to the wear and tear idea, this theory says you are born with a certain amount of energy. If you live fast, you die young, because you use up your energy reserves sooner. laid-back people, who suffer from less stress and take life easier, would live long-lasting should this theory prove correct (Ward 2012).A strong immune system is your bodys most important defense against germs and toxins. White cells engulf and destroy potential pests such as bacteria and viruses. And they manufacture antibodies, the soldiers that patrol the bloodstream, attacking and disarming any substance they dont recognize as the bodys own. Problem is, the immune system becomes less efficient with time, and fewer antibodies are produced, increasing your infection risk. Whats more, the body may turn on itself by producing antibodies that destroy its own tissue.When that happens, autoimmune disease, such as lupus and rheumatoid art hritis, is the result (Alston, 2008). Although we still do not all told understand the process of aging, we do know quite a attraction about it. Sometimes it may be time for the clock to dear get new batteries or perhaps the clock has stood the test time and became an antique. Bibliography Alston, Maude H. Basic Gerontology.
