Explain Physiology of Ageing

Ageing in simple terms refers to a physiological process that occurs in an organism as it gets older Ageing physiologically refers to the impaired ability to maintain homeostasis in the face of external or internal challenges or stresses Hence, the individual becomes more vulnerable to those changes and stresses and thus succumbs to the end of life. The rate by which functional deterioration occurs in various parts of the body is neither simultaneous nor they are perpendicular in pattern. Hence, ageing process implies progressive deterioration of cells, tissues, organs and their functioning associated with increased age.
