The body of a human physically and mentally changes as we grow older. Once a person reaches adulthood, they begin aging causing the body to transform during the time of reaching maturity and the individual’s death. Physiologists have discovered that organs such as the heart, brain, kidneys, or lungs decrease in function as an individual’s life span increases. A younger individual’s body can fight off diseases better than an elder person. This is all due to the fact that as cells age, they function less as well. The amount of hormones produced changes in the body over time. Some chemicals in the body blood levels increase whereas others decrease. Hormones are produced by the organs of the endocrine system and then released into the bloodstream. Hormones control target organs in the body, but as the body ages the amount of hormones produced and …show more content…
As we get older the enzymes decrease which impairs the digestion process in the elderly. Some say that fat absorption also decreases as we get older. Because of poor digestion and decrease in enzymes there is also a decrease in the absorption of vitamins and minerals. Some of the more common deficiencies are protein, calcium, iron, vitamin K, and thiamin. Also, after the age of 50 years old the cells become less sensitive to insulin. Other things that are affected as we get older is our sense taste. This is because there is a loss of cells or atrophy of the taste buds in the tongue. Our sense of smell may or may not change there isn't any substantial evidence on either one. Another change is a slowing in reflexes in the body. One of the most evident changes that can be seen with the eye is the change in elasticity of the skin. This is evident because of the wrinkles we see. This is because of the decrease in elastin which is the fibers that help the skin remain close to the tissues below. Without elastin skin becomes loose and wrinkles. Skin also becomes
Changes due to the aging process also need to be addressed. Calcium reabsorption increases especially in women after the menopause, this decreases bone density. Lean tissue decreases as fat increases with age; there is also a decline in the percentage of body water meaning that body temperature is more difficult to control. Thirst decline and decreased renal function means that older people can become dehydrated (Copeman 1999). The function of the bowel reduces, meaning that the elderly are more susceptible to indigestion and constipation. The risk of constipation is also increased with Parkinson’s disease (Parkinson’s UK 2011). The final consideration is the deterioration of the sensory system. Taste, smell, vison, pain and touch all decline meaning that food may not be as appealing (Copeman 1999).
There are many physical changes that happen during the late adult years. These include vision, hearing, taste, smell, touch, height and hair. In late adulthood your vision is more likely to get worse. There are many different things that can happen with your vision. Along with vision, hearing is also affected. Hearing is affected by many different components. You can lose the ability
Middle-aged adults begin to show visible signs of aging. Vision usually changes and many who did not need corrective lenses or eyeglasses may find that they need them. Hearing loss begins, especially at the higher frequencies. Height begins with the maximum height from young adulthood but then begins to diminish. This process is more rapid in women who have osteoporosis. Changes occur in the nervous system and reaction time slows. The ability to perform complex tasks remains intact. Those in middle age usually begin to gain weight, 5–10 kg (10–20 lb) and experience a decline in strength and flexibility. Women in late middle age experience menopause. Menopause can have many side effects, some welcome and some not so welcome.[2] Menopause ends
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
As we age, our brain and nervous system go through natural changes. An aging adult may experience memory loss, decreased touch sensation, change in the perception of pain, change in sleep pattern, decreased coordination and increased risk for infection (Ignatavicius, 2013, p. 912) .
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,
Elderly people physically slow down and have lower energy levels. There are changes in the body systems and organs that can usually result in all types of
There are many factors that contribute to the vast differences in physical function in the aging adult. One of these factors is related to immunity. As we age our immunity progressively declines putting us at a high risk for disease and illness. While the decline is gradual it has the snowball effect. The elderly population is much more likely to be affected by these diseases and illnesses (Health, 2011). Disease is believed to accelerate aging biologically speaking (Spirduso, 2004).
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
“The skin is the largest, most visible, and most complicated of the body systems. In an average adult, it covers more than 3,000 square inches and weighs about six pounds. It is served by one third of all the blood circulating the body” (Saxon, 2010, p. 17).The skin has many functions in which one needs in order to stay healthy and living. The skin protects the underlying tissues and structures of one’s body, and prevents them from drying or obtaining an excessive loss of water and electrolytes. It also regulates the temperatures in the body through mechanisms such as sweating and shivering. Acting as a physical, chemical, and biological barrier, the skin protects from harmful bacteria and foreign substances contacting with the body. Most importantly,
Psychological changes during old age are interrelated factors occur that have a significant impact on psychological changes during aging. Anatomical and functional modifications in the nervous system and sense organs, modifications in cognitive functions and modifications in affectivity: losses, motivations, personality. Psychological changes may be subject to subjective perceptions of both the person who manifests them and the person who can evaluate them. There are people who live with serious concern the decline of some functions and others who do not value it properly. In general with aging there is a decline and a slowing of cognitive abilities, although there is enormous variability and depends on numerous factors (educational level,
As individuals age changes occur physiologically that are part of normal aging. These changes occur in all organ systems and can impact an individual’s quality of life. The changes related to aging can be attributed to an individual’s genetic make up, lifestyle, physical activity, and dietary lifestyle. Being able to differentiate between normal changes in aging against disease process is important because it can help clinicians develop a plan of care (Boltz, Capezuti, Fulmer, & Zwicker, 2012). Creating an accurate plan of care for older adults will greatly impact their quality of life.
As age increases, we can expect some loss of heart, lung, joint, and sexual functioning. Some loss of brain cells and mental efficiency is a normal part of
As we age, we experience a reduction in the production of hydrochloric acid, digestive enzymes, and saliva, as well as a reduction in the total number of taste buds. These changes can result in:
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.
