Systemic Aging

Meaning

Systemic aging refers to the generalized, progressive decline in the structural integrity and functional capacity of an organism’s various biological systems and organs over the lifespan. This biological process is characterized by a gradual loss of physiological reserve and homeostatic robustness, affecting the body’s ability to maintain optimal function and adapt to stressors. It represents the cumulative impact of cellular and molecular damage that contributes to age-related changes.
