<p>Senescence is the biological process of age-related deterioration in function. It manifests as dozens of changes in cells, tissues, and organs during aging. Human life is supported by a complex network of biochemical substances and reactions which affect the physical state and vitality of the body and mind. Senescent changes can be seen in the rate and outcome of many of these reactions.</p> Signup and view all the answers

<p>Ageing and longevity vary between species, with some organisms exhibiting non-ageing characteristics. For example, the Bristlecone pine has a maximum lifespan of around 5000 years, while the Dahlia anemone is considered non-ageing. Additionally, human longevity is exemplified by Mme Jeanne Calment, who lived to be 122 years old.</p> Signup and view all the answers

<p>The field of gerontology involves the study of aging and plays a crucial role in understanding the processes of senescence, life span, and life expectancy. It provides insights into the biological, biochemical, and physiological aspects of aging, contributing to the comprehension of variations in longevity among different species.</p> Signup and view all the answers

<p>Maximum lifespans in mammals, such as the Bristlecone pine and human longevity, highlight the diverse range of longevity across species. These examples underscore the complexity of aging and longevity, and the potential for non-ageing characteristics in certain organisms.</p> Signup and view all the answers

<p>Senescent changes impact the physical state and vitality of the body and mind through their influence on the complex network of biochemical substances and reactions that support human life. These changes can be observed in the rate and outcome of various biochemical reactions, reflecting the intricate interplay between aging and the overall well-being of an organism.</p> Signup and view all the answers
