What happens to the respiratory system as it ages?

ANSWER:

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
