Aging is a process through which organism’s functionality decline systematically. The decrease in human organism is due to genetic cellular and molecular modifications. The level of changes on the longevity of the plant can affect it in several ways in a gradual process as the age progresses with time. According to Finch, the process of aging can also have a definition that it is the accumulation of underlying molecular errors (Finch,2007). These errors with time eventually corrupt the adult stem cells. The effect of the accumulating errors is due to some epigenetic and genetic interactions (Finch, 2007). Lerner found out that the genetic interactions rely on the heredity, stochastic and environmental factors (Lerner et al, 2013). The …show more content…
Genetic predisposition factors come from biological conditions that one person claims through their heredity (Lerner et al, 2013). Some of these conditions can have an effect on how people think and behave due to the genetic predisposition. A good example is some traits such as theft and alcoholism that people of a given family have either in a past history or in the long run for future preferences. The behaviors may be due to biological factors but not traits that effect the growth and development process (Lerner et al, 2013). Aging on the other hand is a process that affects the human and other organisms’ as a whole. It is, therefore, basically, the adding damages of tissues, cells, and molecules during the process of growth and development. It is a process that takes place in a lifetime span. The changes in the psychological process are permanent (Finch, 2007). The changes will, therefore, affect the way the organism balances the homeostasis process in the body. (Finch, 2007) The body then begin to become immune to the stress conditions in the long run. The declining capacity of the body to maintaining a balance in the homeostasis process is a risk condition to the health of the organism (Finch,2007). It is the reason the body becomes prone to diseases and complications. Some of the severe health issues that occur due to

There are various genetic changes that people can experience the ill effects of that will presumably never be finished unless we effectively mediate and genetic engineering the cutting edge to withstand these issues. Case in point, Cystic Fibrosis, a dynamic and risky sickness for which there is no known cure, could be totally cured and annihilated with the assistance of particular genetic engineering, so it can almost never aging effect humans.
As you begin to get older your muscles within your digestive tract can start to become really weak and would possibly start giving you the risk of having a lot of constipation. Also as you get older your heart is beginning to get less efficient and would not be able to pump the blood around your body like what it used to have done. Also the other things that could happen to your organs as you begin to get older are
The hereditary influences that affect our human development come from predisposed genetically transmitted roots. These factors such as a person 's weight, appearance, height, and muscular composition are not influenced by any external sources. These genetic factors can play a part in how a person feels about them self during their life.
Unit 4 P5 Explain the physical and psychological changes which may be associated with ageing.
2. The MSNBC webcast recounts different stories of the aging population in America. One of the cases mentioned in the web cast is Arden peters and his wife Maxine. The aging theory of wear and tear can be applied to the case of Arden peters who has lost his wife Maxine due to dementia and Parkinson’s. He himself became too weak to care for himself due to the process of aging (MSNBC, n.d). He reached a point where he required someone to care for him. His friend Warren DeWitt is taking care of him and previously helped him take care of his wife until she passed away (MSNBC, n.d). The theory of wear and tear is based on the notion that aging is caused by damages done at the cellular level over time (Hawkley, Berntson, Engeland, Marucha, 2005). The processes that could damage the cells could be sickness, radiation, and accumulation of toxic materials over time
Humans undergo several stages during their lifetime including growth, development, reproduction and senescence. Senescence is defined as the deteriorative biological changes that organisms experience as they age eventually leading to death. These changes include low metabolism, a weak immune system, memory loss, poor vision and loss of hearing. Senescence begins in humans during their post-reproductive years. However, gerontology research has shown that individuals who reproduce late have longer life spans compared to individuals who reproduce early. Nonetheless, it does not indicate that senescence is inevitable. All organisms experience senescence,
Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence? Clearly exploration of the nature versus nurture argument with regard to genetic predisposition has social, political, and legal significance.
In order to better understand aging-associated diseases, it is first necessary to define what aging is. Aging is a complex, multifactorial process of harmful mutations in cells and tissues that are accumulated over time and result in an increased risk of disease and, eventually, death (Tosato, Zamboni, Ferrini, & Cesari, 2007, p. 401). Contrary to the belief that aging can be cured through medical advances, it is scientifically accepted that, while human life expectancy has increased, the human life span has remained largely unchanged for the past 100,000 years (Tosato et al., p. 401). Therefore, future developments in aging research ought to focus on addressing treatment and prevention of major aging-associated diseases that will
A person’s nature, or genetics, determines aspects of the psychology of a person before they’ve been born. There are many example of how genetics determine characteristics of a person, regardless of the environment, also known as
The world of Genetics is one that is both fascinating and interesting. When tackling how genetics plays a role in behavior, one must look within the scope of what genetics is before dealing with how it plays a significant role in one’s behavior. Simply put, genetics is the study of genes. It is a biological component within the entire study of biology itself. Scientists who study genetics and perform research do so with the intent to learn more about how genetics affects the overall attitudes, behaviors and dispositions of individuals. It could be said that genetics is somewhat of a psychological-biological science as researchers look at the underlying patterns within the genes that cause
According to the article "My Genes Made Me Do It” by Stanton Peele, Ph.D, and Richard DeGrandpre, Ph.D, “The goal of determining what portion of behavior is genetic and environmental will always elude us. Our personalities and destinies do not evolve in this straightforward manner” (Peele). Many factors can influence behavior, and behavior is not simple. It is very complex and can in some cases cause people to behave criminally. There are genetic factors that can influence a person’s behavior as well as environmental factors. All of these factors should be considered when looking at criminal behavior. The factors that affect a persons likelihood to commit a crime include genetic and environmental influences, but there are ways to prevent crime.
The way God created us as humans is a life cycle where eventually late adulthood comes with the biology of aging. Santrock (2013) describes five different theories of why humans age (p. 541). The evolutionary theory explains that aging is more of a natural selection process, and diseases occur in the elderly because they “would have been eliminated” if they were in younger people (Santrock, 2013, p.541). Cellular clock theory describes how cells get tired of dividing after they have been reproducing for so long (Santrock, 2013, p.541). Free-radical theory explains when “cells metabolize energy the by-products include unstable oxygen molecules known as free radicals” (Santrock, 2013, p.541). The unstable oxygen molecules can damage DNA and other structures inside the cell (Santrock, 2013, p.541). Mitochondrial theory describes how aging occurs because of the mitochondria essentially wearing out and becoming less efficient (Santrock, 2013, p.542). Mitochondria are the cell’s “power house,” and they convert energy inside the cell (Bailey, 2008). The last theory, hormonal stress theory, illustrates the effects of stress, especially long term stress, on aging (Santrock, 2013, p.542). Stress released hormones which depress the immune system making people more susceptible to disease (Santrock, 2013, p.542). There are many theories about why human’s age, and all of them may be true, but regardless aging is inevitable and so are its effects.
Aging is the process of becoming older, as we age, multiple mutations occur that concern all the processes of aging well as it compromising a number of different genes. There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a “biological clock that determines its maximum life span” and how quickly one 's health will deteriorate(Hooyman, 42). After a certain number of years, each cell which follows an apparent biological clock starts to replicate itself less, thus the specific individual or species slowly deteriorates. This theory gives
Also spelled as ageing, this is generally the process of becoming old. It is the in a way the opposite of immortality. In a broader aspect, it may occur to single cells in an organism also called cellular senescence or the population of a species, known as population ageing. This process primarily affects human beings and fungi. In humans, it signifies the accumulation of various changes which occur over time. The changes include physical, social and psychological changes.
