Ageing Process

AGEING PROCESS

The ageing process is the gradual, decreased ability of the body to functions and to heal itself.

As our body age, they naturally deteriorate in the late years, many essential functions begin operating at a suboptimal level.

There are three main factors that influence the body’s ageing process.

First as we grow older, the number of mistake incurred by daily Cellular reproduction increases. The body actually create non-functional cells, leading to more rapid deteriorate of the body’s functions with advantage age. A large percentage of our cells even through they were present are useless. These non-functional cells sometime interfere with normal cellular process.

The second part of the ageing process related to Cellular damage that cause the shortening of DNA. As time passes increased damage to healthy DNA leeds to accelerated cell death and our old bodies simply cannot generate cells fast enough to compensate for the loss. This process is most visible and obvious in our skin the older we get the thinner our skin becomes

The third part of the ageing process involves the Cellular deconregulation of our national oxidative enzymes such as superoxide dismutase and catalase and glutathione perxoidase, making our antioxidant defence less efficient with age.

The Ageing Process Starts in Human Organ

From the moment of birth human beings experience continuous aging, however before the age of 25 the body can recover from temporary con sequencence by itself, after 40 years old the ody begins its real journey of ageing.

Common Signs and Symptoms of Ageing

·           Increase susceptibility to infection.

·           Greater risk of heat, stroke of hypothermia.

·           Slight decrease in height as the bones of our spine get spinner and the lost some height.

·           Bones break more easily.

·           Joint changes ranging some minor stiffness to severe arthritis.

·            Stooped posture.

Mechanism of Ageing

Biological Process of Ageing

·           The genes determine the lifespan, genes may have a role to play in the ageing process.

·           Wear and Tear of important organs by continues functioning .

·           Accumulation of toxic materials (E.g.. cholesterol) in the vital organ like heart, brain eye and thereby damaging them.

·           Loss of important genetic material during DNA repair.

·           Accumulate of stress over lifetime with its resultant effects.

·           Exertion of production and deficiency of important hormones e.g. growth hormone and androgen, oestrogen and thyroid hormones.

·            Evaluation of ageing helps to explain why survival, reproductive success, and functioning of almost all living organism decline at old age.
