Indeed, according to the Cancer Research UK website, ″Older age is the most important risk factor for cancer.″ This is mostly due to the accumulation of DNA damage in cells over time. There is the possibility of damage resulting from biological processes or from exposure to risk factors’.
Which of the following is are typical consequence’s of aging?
Hearing loss, cataracts, and refractive errors, back and neck pain, and osteoarthritis, chronic obstructive pulmonary disease, diabetes, depression, and dementia are among illnesses that often affect older people. For more information, visit www.cdc.gov. As people get older, they are more prone to suffer from a number of different ailments at the same time.
Which of the following changes are associated with aging except?
All of the changes listed below are related with the passage of time. With the exception of reduced hormone secretion in general. WITHOUT RULE, reduced parathyroid hormone is a problem.
When specific genes switch off before age related losses What is it referred to as?
A condition known as planned senescence occurs when particular genes are turned down prior to age-related losses occurring.
Which type of theory emphasizes aging as a result of random damage?
Several theories of aging have been proposed, including the wear and tear hypothesis of aging, which says that the consequences of aging are produced by gradual damage to cells and bodily systems over time. 1 In essence, our bodies ‘wear out’ as a result of constant use. Once they have reached the end of their useful life, they can no longer work properly.
What factors affect the aging process?
Sun exposure and smoking were the two most significant external variables that influenced the degree of aging. In addition to alcohol intake and stress, other potentially contributing lifestyle variables include food, exercise, illness, and prescription medication.
What are the major causes of aging?
- The Causes of Aging Collagen degradation is one of the causes of aging. This substance accounts for approximately 75% of the dry weight of the skin. Premature skin ageing, skin damage, and skin cancer are all caused by repeated exposure to ultraviolet light (UV radiation) from the sun, which accounts for over 90 percent of the symptoms. Oxidation. Inflammation. Glycation
What is an age related change in the body system of the older adult?
Abstract. Physiological changes occur in all organ systems as a result of the aging process. Cardiac output declines, blood pressure rises, and arteriosclerosis occurs as a result of this. It is evident that the lungs have poor gas exchange, a reduction in vital capacity, and slower expiratory flow rates.
What is an expected change in the cardiovascular system that occurs with aging quizlet?
Deposits of the ‘aging pigment,’ lipofuscin, are among the normal changes that occur in the heart. The cardiac muscle cells have a minor degeneration. Thickening and stiffening of the heart valves, which govern the direction of blood flow, occur during the course of the disease. It is fairly typical in elderly adults to have a cardiac murmur as a result of valve stiffness.
How do our dietary needs change as we get older?
When compared to younger persons, the calorie requirements of older adults are lower, but their nutritional requirements are equal or even higher. This is frequently caused by a lack of physical activity, changes in metabolism, or the natural decline in bone and muscle mass that occurs with aging.
How do telomeres factor into biological aging quizlet?
Telomeres are found at the ends of chromosomes and act as a protective ‘cap’ to prevent the ends from being destroyed or shortening. Eventually, there is so little left that the cells are unable to replicate at all. The rise in the number of senescent cells also leads to the development of age-related disorders, the loss of function, and the occurrence of premature death.
What is the single most important factor that enables older adults to live in their own homes instead of in institutions quizlet?
What is the single most essential feature that permits older individuals to remain in their own homes rather than being institutionalized or assisted living facilities? People who are in poor health or have impairments and require a great deal of care
Which theory of successful aging suggests that older adults should continue to do what they have been doing as long as they find that activity satisfying?
A third important notion in good aging is continuity theory (Atchley, 1989). This concept might be used to mental aerobics for older persons, according to Atchley. Following the logic of continuity theory, an individual’s current actions, learning, and related tasks should be a reflection of his or her previous activities, learning, and associated tasks.
What are the three major theories of aging?
Specifically, three key psychosocial theories of aging are discussed and evaluated: activity theory, disengagement theory, and continuity theory (in that order).
Which of the major theories of aging suggests that older adults may decelerate the aging process?
It is known as the Damage or Error Theory. Third, according to cross-linking theory, a buildup of cross-linked proteins harms cells and tissues, slowing down body functions and ultimately resulting in the aging of the individual.
What is the evolutionary theory of aging?
As people become older, they have less lifetime fertility left, which means that continuing existence contributes less to reproductive success according to the standard evolutionary theory of aging. While fertility and intergenerational transfers are important components of successful reproduction, they are not always necessary.
