mammalian aging

Mammalian aging involves gradual changes in cells and tissues that reduce an organism’s ability to function effectively over time. As mammals age, damaged molecules and cells accumulate, leading to decreased tissue repair, weakened immune responses, and declining organ performance. Genetic factors influence how quickly these changes occur, and environmental factors can accelerate or slow aging. Overall, aging results from complex interactions between genetic programming and environmental influences, leading to the gradual decline in physical and biological functions characteristic of older mammals.
