The above explanation of digestion occurs in a ‘normal’ functioning body. There are several dilemmas involving digestion that the human body may encounter with progressed age, disease, or improper mechanics, such as lack of teeth. A major threat involving a decrease in digestion ability is malnutrition. Malnutrition does not simply refer to not eating, but also encompasses insufficient absorbance of nutrients once food has been eaten. There is a wide array of factors that may lead to malnutrition in an individual. Mechanically, the lack of teeth is a simple but yet common reason of decreased nutrition intake. Though salivary glands are stimulated upon the introduction of food to the mouth, a person with no teeth tends to avoid the more strenuous foods to chew, such as meats, carrots, lettuce, and nuts, and become partial to a lot of soft foods like potatoes and eggs, which may not necessarily be the most nutritious or balanced. Individuals with gum disease may have all their teeth, but it can become sore for them to chew their meals and, as a result, the eating dwindles. Jaw injuries or surgeries can cause discomfort and may temporarily hinder proper

As my grandmother got older she went through many physical changes due to hormones in her body. At the age of 50 she went through menopause and this meant that there was many physical changes in her body like her periods started to become irregular and after a while would stop. The oestrogen hormone levels in women would decrease when they go through menopause. There are other symptoms which my grandmother experienced like:

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

Normal aging is a gradual decline in certain processes (Gladyshev, & Gladyshev, 2016). The decline is not static and can be increased or reduced depending on choices made (Gladyshev, & Gladyshev, 2016). Changes commonly attributed to aging include declines in the five senses, most organ systems, appearance and brain function (Tully, 2016). The five senses include reduction in taste buds, smell, ability to hear high frequency sounds and speech discrimination, reduced ability to see in the dark and a reduction in tactile sensory (Tully, 2016). In the organ systems there is a reduction in the hearts response to work, bone mass, skin turgor, vital capacity in the lungs, renal and colon function (Tully, 2016). Most notable is the age-related changes

This shortening is believed to cause the cell to duplicate itself incorrectly. Because each time it duplicates itself it’s a little worse than the previous time, this eventually leads to cellular dysfunction which they believe leads to aging and eventually death.

Several major physical and mental changes occur with aging. One physical change being in the cardiovascular system as heart rate decreases and arteries and blood vessels become firmer, causing the heart to have to work harder in order to pump blood to the rest of the body. These changes can cause several cardiovascular problems such as high blood pressure. A second physical change being in the bones, joints, and muscles. With age, bone density and size decreases which makes them less durable, more susceptible to fracture or break, and may even decrease one’s height. Muscles also lose strength and flexibility with age, causing coordination and balance to be altered. A third physical change being in the digestive system as constipation is a common

Ageing is the process of becoming older. As humans beings get older, the body system and functions will gradually progress towards deterioration. There are two factors that influencing the aging process which is intrinsic and extrinsic. The intrinsic factors is influencing by the internal physiological factors alone while the extrinsic factors is caused by external factors such as ultra violet radiation, cigarette smoking, air pollution and other. Intrinsic factor also called as a chronological aging and extrinsic factors called as photoaging.

Healthy digestion is crucial for health and wellbeing. Everything we ingest has a purpose, either it will nourish the body and act as fuel or will lead to various health conditions, some can be minor but while some lead to chronic disease. If our digestive system is not working properly, even with the best diet, nutrient absorption will be reduced.

As you age, body changes start taking place. Unfortunately, you cannot stop those changes. For example, the skin becomes less elastic and more wrinkled. Oil glands slow down, therefore, making skin drier. Vision becomes affected as well, it is normal for night vision and visual sharpness to decline. Hearing loss also occurs with aging. Sleep

There are many broad theories that aim to explain why and how we age. These theories generally compete with each other and typically only focus on one or a few aspects of aging. To truly have a comprehensive aging theory, one must look to multiple theories, both biological and social. For my theory, components from the free radical, immunological, modernization and continuity theories are utilized.

The process of digestion in the human body is a set of successive functions aimed at

Biological changes are probably the most noticeable change to an individual in regards to the topic of aging. This theme looks at how old the individual seems to be by measurements of how well the body is performing. Variables can range from vitals such as heart rate, blood pressure or lab tests like glucose levels and liver function to any other factors that play into allowing the individual to perform various activities of daily living. According to a research report done on whether limitations where were more prevalent towards a population between 55 to 69 were not statistically significant in terms of vision, hearing, cognitive functioning, and ADLs (Choi, Schoeni, & Martin, 2016). The researcher studied more than 72,000 subjects between the years of 1998 to 2012 in the United States. Data collection was done through a longitudinal survey either over the phone or in

In exploring module 5, much information was able to be learned about the structure, function, and age associated changes or dysfunctions of both the digestive system and the urinary system of the human body. Although through the exploration of this module, I have learned that the digestive system and the urinary system are comprised of their own distinct features and functions, I would say the most significant knowledge I have gained from module 5 would be that of the digestive system. More specically, the most significant knowledge that was gained of the digestive system itself, was that of the actual digestive processes. The process of digestion is a complex series of activities including ingestion, propulsion, mechanical or physical digestion,

LeVay and Baldwin (2012) listed several physical changes for both men and women as they continue to age. For women, as they age they

Senescence in the phrase “effects of senescence on physiology”, refers to the complex process of ageing that eventually leads to death. Therefore, effects of senescence to physiology refers to how biological processes and organs within the human body change as a result of one growing old (Shock, 2015). In addition, the author points out that the performance of organs such as heart, kidneys, brains or lungs decreases as a result of cell death due to the decreased ability of the body to produce or repair cells- when one is growing old. Shock (2015) mentions that during senescence the remaining cells in the elderly body may not perform as well as those in a young individual thus, taking enzymes in the elderly body to carry out chemical reactions.
