| Aging Process |  Aging is a time-consistent deterioration of all organism. It includes weakens, increased sensitiveness to disease and unfavorable environmental conditions, loss of mobility, and age-related physiological changes. Aging also includes lowering in breeding capacity. It is a period of changes that are harmful, gradual, general and thus far irrevocable.
Molecules, cells and organs are subjected to aging changes. People of older age are more likely to suffer from such diseases as osteoporosis, arthritis, cancer, heart disease and others. But even if aging process is separate from the disease of aging, it is still true that the aging process causes changes that increase the chance that diseases of old age will occur.
People reach a pick of growth and development about the time of their mid 20s. Aging is a normal passage time after that burst of activity. Although there are several age-related changes that weary the body, incapacity is not certainly a part of aging. The response to these changes is determined by health, lifestyle, and genetic wakeup of the individual.
The following body functions are most often affected by aging:
- Hearing becomes worse especially in relation to the highest pitched tones.
- The amount of fat increases in 30%. It thins out under the skin and gathers around the stomach. The ability to disgorge fats is impaired, and therefore the accumulation of fats increases, involving fat-soluble nutrients and cholesterol.
- The kidneys and the liver cannot function as rationally, thus affecting the removal of wastes.
- The level of water in the body lessens, consequently decreases the absorption of water-soluble nutrients. There is also less spittle and other lubricant fluids.
- A slump in the ease of digestion, with a slump of stomach acid.
- A loss of coordination including loss of mobility, flexibility, and agility.
- A decrease of muscles strength.
- The sensations of smell and taste decreases.
- Sexual hormones and sexual functioning declines.
- Declined functioning of the nervous system in such way that nerve impulses are not transmitted as rationally, reflexes are not as quick, and learning and memory are reduced.
- A lack of oxygen and nutrient throughout the body occur because of changes in the cardiovascular and respiratory system.
- Bone strength and density decreases.
- A visual ability declines. Aging changes may cause a macular degeneration.
- Hormone levels decline little by little. The thyroid gland and sexual hormones are especially affected.
- The ability to produce vitamin D from sunlight decreases.
- Osteoporosis may develop because of the protein formation reduction.
