What term refers to the universal, irreversible physical changes that occur as organisms grow older?

Explanation:
Primary aging refers to the universal, irreversible physical changes that occur as organisms grow older. These changes arise from intrinsic biological processes and happen in everyone over time, regardless of disease or lifestyle. They are the baseline aging that cannot be fully prevented, only managed. By contrast, secondary aging results from disease, injury, or environmental factors and can often be slowed or avoided with good health habits. Tertiary aging describes a rapid decline in function near the end of life and is not a universal stage of aging.
