The aging process has a major impact Biology essay
Introduction - a brief overview of the field. Aging is a complex biological process characterized by hallmarks that accumulate over the human lifespan, including mitochondrial dysfunction, telomere attrition, epigenetic changes, genomic instability, loss of proteostasis, cellular aging, metabolic imbalance, stem cells. Chronological age refers to how long you live. you have lived, while biological age refers to how old your cells and tissues are. It is possible that your biological age is lower than your chronological age if you are in good health and fit for your age. A sedentary lifestyle, chronic diseases and poor physical health can increase biological age. Others are based on the idea that aging follows a programmed timetable and has an upper limit. No single theory or phenomenon seems to fully explain why aging occurs. Researchers generally view aging as many processes that interact and influence each other. Here are some of the biological processes that appear to be occurring: A. Methodological issues in the study of aging skeletal muscle. Research into sarcopenia in humans is complicated by the long duration of the aging process, high variability between individuals, and multiple factors affecting muscle that are not necessarily primarily related to aging. Research on aging can be carried out using a cross. Age is one of the most important risk factors for cancer. Several biological changes related to the aging process may explain this. Because our population is getting older, the proportion of older patients with cancer is increasing significantly. Due to the heterogeneity of general health and functional status in the elderly, treatment, aging, progressive physiological changes in an organism leading to aging, or a deterioration of biological functions and of the organism's ability to adapt to metabolic stress. Aging occurs over time in a cell, an organ or the entire organism. It is a process that continues throughout the adult life span of each life,
