Effects of aging on the respiratory system


  • The effects of aging on the respiratory system are similar to those that occur in other organs: maximum function gradually declines. Age-related changes in the lungs include

    • Decreases in peak airflow and gas exchange
    • Decreases in measures of lung function such as vital capacity (the maximum amount of air that can be breathed out following a maximum inhalation)
    • Weakening of the respiratory muscles
    • Decline in the effectiveness of lung defense mechanisms

    (See also Overview of the Respiratory System.)

    In healthy people, these age-related changes seldom lead to symptoms. These changes contribute somewhat to an older person
