The respiratory system decline earlier and more obvious, because the respiratory system is the gateway to the outside world, often by the polluted air stimulation. Respiratory aging is manifested by mucosal atrophy; epidermal ciliated epithelial cells decreased cilia shedding; secretory cell dysfunction
