Rate of living theory , that supports the theory that the greater an organism’s rate of oxygen basal, metabolism, the shorter its life span. Cross-linkage theory, according to which an accumulation of cross-linked proteins damages cells and tissues, slowing down bodily processes and thus result in ageing.
Which theory attributes aging to our body organs in cell tissues simply wearing out with repeated use and abuse?
The wear and tear theory basically states that our bodies wear out after time.
Which theory or theories of aging suggests that aging is genetically determined quizlet?
Error theory proposes a genetic determination for aging. This theory holds that genetic mutations are responsible for aging by causing organ decline as a result of self-perpertuating cellular mutations.
Which of the following is a biological theory explaining aging?
Choice, Aging occurs because cells produce unstable oxygen molecules that damage DNA. ... Cellular theory, also known as telomere theory , holds that cells can divide a maximum of about 75 to 80 times and that as people age, their cells become less capable of dividing.
What are some theories of why aging occurs quizlet?
Programmed theory is the idea that aging is genetically programmed to occur with time, and this process of deterioration eventually leads to death. Damage theory is the idea that external or environmental forces gradually damage cells and organs, leading to aging and death.
What are the two main theories for aging?
Modern biological theories of aging in humans currently fall into two main categories: programmed and damage or error theories .
What are the three major theories of aging?
Three major psychosocial theories of aging –activity theory, disengagement theory, and continuity theory– are summarized and evaluated.
What is cellular aging theory?
Cellular theories of aging propose that human aging is the result of cellular aging , whereby an increasing proportion of cells reach senescence, a terminal stage at which cells will cease to divide. This will limit the body’s ability to regenerate and to respond to injury or stress.
What are some theories of aging?
- Disengagement Theory.
- Activity Theory.
- The Neuroendocrine Theory.
- The Free Radical Theory.
- The Membrane Theory of Aging.
- The Decline Theory.
- The Cross-Linking Theory.
What is immunological theory?
The immunological theory of aging asserts that the process of human aging is a mild and generalized form of a prolonged autoimmune phenomenon . In other words, aging—which involves a highly complex series of processes—is suspected to be largely controlled by the immune system.
What are the three types of aging?
There are three kinds of aging: biological, psychological, and social .
What is an example of disengagement theory?
An example of disengagement theory if an older adult who has heart disease may develop shortness of breath may be unable to continue daily walks with their friends . ... Another example of disengagement theory if when a retired career women experience loss of social network and self-satisfaction of work.
What are the four types of aging?
As of October 2020, Snyder’s team has identified four distinct ageotypes: metabolic agers , or people whose immune systems age fastest; immune agers; kidney (or “nephrotic”) agers; and liver (or “hepatic”) agers.
What are the major theories of aging quizlet?

- Genetic Theories of Aging. ...
- Wear and Tear Theories. ...
- Immunity Theory of aging. ...
- Cross-Link Theory of Aging. ...
- Free Radical Theory. ...
- Neuroendocrine theory. ...
- Apoptosis Theory.
What causes aging quizlet?
Aging is the result of a sequential switching on and off of certain genes , with senescence being defined as the time when age-associated deficits are manifested. This theory suggests that biological clocks act through hormones to control the pace of aging.
What is the activity theory of aging quizlet?
Activity theory. -According to Activity theory, successful aging occurs when people maintain the interests, activities, and social interactions with which they were involved during middle age . -Happiness and satisfaction with life are assumed to spring from a high level of involvement with the world.
