Mechanisms of aging and cellular senescence
Aging is a syndrome that occurs as a result of changes that are progressive, deleterious, universal and therefore, irreversible. This aging damage occurs to the cells, molecules that forms the cells, and to the entire organ. The aging process is most commonly associated with old age diseases such as osteoporosis, arthritis, cancer, heart disease and Alzheimer's disease among others; this is because such diseases are associated with degenerative effects experienced by the cells. Scientist have over the years substituted the word ‘aging' with ‘senescence' since aging means that when time elapses so does deterioration takes place which is false especially during the early developmental stage
