HS 2211 - Human Anatomy and Physiology Discussion Forum Unit 1 As individuals age, a variety of systems begin the decline to the point where an individual's functioning is compromised. Identify and discuss two factors that have a role in factors leading to the compromised situation. Your Discussion must be at least 250 words in length, detailing your thoughts and position using 2 references from the readings for support. Also, be sure to pose 1-2 well-thought-out questions from which your colleagues can formulate a response or generate further discussion. Be sure to cite any references using APA format. The 1950s saw the initial formulation of the free radical hypothesis on aging, which is still up for discussion today. According to the free radical hypothesis of aging, oxidative stress-induced cumulative cellular damage is a factor in the physiological and anatomical impacts of aging. One variant of this hypothesis contends that oxidative damage results in aging itself, whereas the other contends that oxidative damage is the root cause of age-related diseases and illnesses. More people accept the second iteration of the hypothesis than the first. The aging process is thought to be aided by oxidative damage, according to a number of lines of research (Openstax, 2018). 1) Lifestyle - A person's lifestyle comprises their nutritional preferences, social interactions, level of physical activity, mental health, and other factors. A person's health and cellular function deterioration are strongly influenced by their dietary habits. For healthy growth and metabolism as well as a number of bodily processes, nutrients (found in food) are essential. A person's health may suffer as a result of vitamin deficiencies, which can hinder several metabolic processes. A healthy and balanced diet is necessary for the cells and tissues of the body. Along with this, the body need a minimum amount of physical exercise each day to stop or delay the onset of age-related health issues. Lifestyle also refers to a person's choice of hobbies. For instance, frequent smoking raises the risk of illness, collagen breakdown, and other conditions while also speeding up some aging processes (including premature skin aging). 2) Genetic make-up - Genetics or genes have an impact on aging. Unrepaired mutations can accumulate over time and shorten life expectancy. According to the "genetic theory of aging," a person's lifetime is mostly influenced by their inherited genes. All of the body's operations are controlled by genes, thus changes to these genes will have a negative impact on cellular processes, which might ultimately hasten the aging process (University & OpenStaxCollege, 2013). My question is as follows: What are the cellular changes due to aging ?
