How does aging generally affect the respiratory system?

As individuals age, a variety of physiological changes occur across multiple systems in the body, including the respiratory system. The general decline in overall lung function is a widely recognized aspect of aging. This decline is attributed to several factors, including a reduction in lung elasticity and the loss of alveolar surface area, which decreases the efficiency of gas exchange.

Additionally, the strength of the respiratory muscles can diminish with age, leading to less effective ventilation. Changes in the thoracic wall, such as ossification of the cartilage and a decrease in rib mobility, can further contribute to these issues. The cumulative effect of these changes results in a decline in overall lung function, making it more challenging for older adults to engage in activities that require increased oxygen intake or exertion.

In contrast, the alternatives presented suggest positive enhancements in respiratory capacity or function, which are typically not associated with the aging process.
