The lungs are getting old, too. Age-related pulmonary alterations are: a decrease in peak expiratory flow or maximum velocity of breath and gas exchange (oxygen and carbon dioxide exchange at each breathing cycle). We can observe a decrease in lung function marked by a decrease in the forced vital capacity (maximum amount of air exhaled after a maximum inspiration), a weakening of the respiratory muscles, a decline in the defense mechanisms of the lungs.

In healthy people, the aging of the lungs is almost unnoticed, although it may limit the practice of intense physical activity. On the other hand, it can accentuate the consequences of certain cardiac or pulmonary pathologies. The alteration of lung function with age is combined in particular with the deleterious effects of tobacco.
