A Brief Summary Of Aging

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

Aging is a beautiful process that should be taking for granted. Growing of age should represent a well-preserved body and mind that exemplify the honor of the aging process. Conclusively, the aging process increases the quality of experience and the splendor of being magnanimous of aging. "The gray hair of experience is the splendor of the old" Proverb 20:29 (New Living Version).

Unfortunately, aging is inevitable, and there is no way to reverse the process. However, the experts believe we can slow it down. But why do people age? According to Kathleen Berger, author of The Developing Person Through the Life Span, “hundreds of theories and thousands of Scientists have sought to understand why aging occurs” (688). The Wear and Tear Theory, “a view of aging as a process by which the human body wears out with age” (Berger), states that once our body wear out, it can no longer function correctly, because “organ reserve and repair processes are exhausted as the decade pass” (689). A range of things can damage some parts of our body system such as “exposure to the elements, or things in the diet, or pollution, or radiation” (Berger, 2014). However, as stated by Berger, this theory does not explain the whole aging process since some body functions benefit from use. “Exercise improves heart and lungs functioning; tai chi improves balance; weight training increases muscle mass; sexual activity stimulates sexual-reproductive system, [and] foods that

Aging is actually the slowing process of cells: using less and less energy or entropy. As we age, our cells don’t regenerate as quickly as they used to. We slow down, our internal systems slow down and we just don’t generate the heat and energy of before. Entropy will envelope our closed system (cell) and it will just not produce as it should.

Hypernatremia is a result of too much sodium in the blood that is >145 mmol/L. It is a common electrolyte problem that is most likely caused by impaired thirst or mental judgment and/or not drinking enough water.

The neurological effects of uraemia include peripheral neuropathy that leads to his signs of pruritus (Bullock & Hales, 2013; LeMone et al., 2013). One of the main roles of the kidney is erythropoietin production (Bullock & Hales, 2013; LeMone et al., 2013). As the function of the kidney decreases and an increase of metabolic toxins occurs, this leads to a decrease in red blood cell (RBC) formation and an overall decrease in the lifespan of the RBC (Bullock & Hales, 2013; LeMone et al., 2013). This leads to anaemia and subsequently low oxygen saturation (Bullock & Hales, 2013; LeMone et al., 2013). This explains his low haemoglobin count, low RBC count, low hematocrit and feelings of malaise and agitation (Bullock & Hales, 2013; LeMone et al., 2013). Mr Goodpasture’s rise in potassium is as a result of a build up of H+ called acidosis (Bullock & Hales, 2013; LeMone et al.,

Everyone wants to stop the process of aging and man has been in search of a product that will help him. A few years ago, researchers found that aging occurs due to the reduction in production of the Human Growth Hormone in the body. As the body ages, the pituitary glands, responsible for the production of HGH, do not produce sufficient quantity of the hormone causing the many signs of aging to appear.

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 two possible causes for this condition that are revealed in the case study. The first cause is that the patient was sick with the flu during which she was vomiting multiple times each day and unable to keep down any foods or liquids, resulting in her becoming dehydrated. This dehydrated state reduces the amount of plasma in the blood stream, causing an alkalemia effect (WHO, 2010). This is further exasperated by the loss of gastric secretions, which are very high in hydrochloric acid. This hydrochloric acid typically enters the bloodstream in small amounts, encouraging the necessary homeostatic state for proper blood

Aging is part of life, as we grow our body changes from the moment we are born we start developing and slowly start to age. The body organs and body system starts developing when we are in our mother’s womb and every day there is a change in our body. As people get older we start having health issues some are moderate but with time it is more likely that does issues will turn into health problems. Aging changes the nervous system, the brain and nervous are your body’s central control. Which means that our body is controlled by the brain. The brain and nervous system control our thoughts, memories, movements and senses. They also help control the organs such as the heart and bowels.

It is secondary to under-perfusion of otherwise normally functioning kidneys and if detected early can be reversible. In Mr Jones’s case, his kidney’s experienced hypo-perfusion during surgery. Hypo-perfusion consequently causes azotemia due to the excess nitrogenous wastes in the blood. Medications, such as high doses of dopamine, can cause prerenal kidney injury due to the production of intrarenal vasoconstriction, which can lead to hypo perfusion of the glomeruli (Nissenson, 1998). The kidneys have an enormous blood supply and account for 20-25% of cardiac output. This blood supply is needed for the removal of waste products and the management of fluid and electrolyte balances. If the blood flow to the kidneys is reduced, this has a decreasing effect on the GFR leading to a decreased urine output, filtration and reabsorption of filtered material through the glomerulus. This can lead to further issues and effect other organs in the body. Fredrick experienced a decreased urine output as a symptom of his reduced GFR. Fredrick’s increased respiration rate noted during assessment was an indicator of his deterioration and alerted the medical team that there was an underlying issue. During the nurse’s assessment, they observed that Frederic had very poor urine output, which is also linked with the drop in the GFR in the kidneys. Thus, encouraging the nursing staff to take immediate action with thereputic

One of the first systems that begins to be affected by the aging process is the muscular system. After the age of 30 in most males, and 40 for most females the body will begin to lose lean body mass or musculature, a process known as atrophy. This occurs as testosterone starts to gradually decrease in males after the age of 30, while women typically experience this during their post-menopausal stages as estrogen decreases abruptly. Bone density and mass is also decreased during this stage due to a depletion of calcium and other essential minerals. The vertebrae are affected by the loss of minerals and often times become thinner, as do the disks between every vertebrae in the spinal column, while they are also compacted and starting to gradually form a more pronounced curvature. All of these taking place in the spine cause a decrease in height. Joints begin to lose mobility and flexibility, fluid within the joints gradually decreases and can cause cartilage to rub together, which lead to discomfort and inflammation

Sodium and potassium transport can be related to kidney function and dialysis. The level of potassium is managed by the kidneys. A balance has to be maintained between sodium and potassium. The main organ that controls the balance is the kidney. By removing excess potassium in the urine, the balance of potassium is controlled. For those that have a kidney disease, some may be told by the doctor to avoid foods that are high in potassium. Kidney losses

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

Causes of aging are very uncertain. Besides, there are several factors which predispose an individual to premature aging. Current theories suggest that this process occurs to due to cellular damage such as DNA oxidation by free radicals causing
