I have to answer this question for my human biology homework. So far I have:

Aging is the process that involves the changing that comes with the passing of time. At around twenty years of age, humans physiologically peak. This is when they’re in their early adulthood. From about twenty to forty years of age, most of the body systems are stable. Forty and beyond is when the human body starts to age faster and faster and the body’s systems and functions start to decline and not work as well as they used to when the body was younger.

I'm not sure what to put for my explanation of the life processes of aging? Any help would be appreciated.

Don't really understand the meaning of "life process", but I did find this article that helps:

Aging is commonly defined as the accumulation of diverse deleterious changes occurring in cells and tissues with advancing age that are responsible for the increased risk of disease and death. The major theories of aging are all specific of a particular cause of aging, providing useful and important insights for the understanding of age-related physiological changes. However, a global view of them is needed when debating of a process which is still obscure in some of its aspects. In this context, the search for a single cause of aging has recently been replaced by the view of aging as an extremely complex, multifactorial process. Therefore, the different theories of aging should not be considered as mutually exclusive, but complementary of others in the explanation of some or all the features of the normal aging process. To date, no convincing evidence showing the administration of existing “anti-aging” remedies can slow aging or increase longevity in humans is available. Nevertheless, several studies on animal models have shown that aging rates and life expectancy can be modified. The present review provides an overlook of the most commonly accepted theories of aging, providing current evidence of those interventions aimed at modifying the aging process.
