There are many age-associated changes in the respiratory and pulmonary immune system.
These changes include decreases in the volume of the thoracic cavity, reduced lung …

With the looming expansion of the elderly population of the US, a thorough understanding of
“normal” aging-related changes on the respiratory system is paramount. The respiratory …

Lung function generally declines with aging. Physiologic alterations are due to the combined
effects of a decrease in lung elasticity, an increase in chest-wall stiffness, and a decrease in …

The prevalence of lung conditions, such as COPD and pulmonary fibrosis, and lung
infections, such as pneumonia, increases sharply with age. The physiologic, cellular, and …

The tissues of the lungs undergo changes with age that lead to an increase in alveolar size
without any destruction of alveolar walls. This lowers the alveolar surface tension and so …

Advancing age is associated with a decline in the integrity of physical barriers and protection
against invading pathogens, and age-related changes in the immune system are associated …

There are now more Americans older than 65 years than at any other point in US history,
and the aging population is expected to increase rapidly over the next decade. 1 Aging …

In this review article, the effects of old age on lung structure and function are discussed.
Changes in lung morphology and biochemistry are correlated with changes in lung …

Lung aging is associated with structural remodeling, a decline of respiratory function and a
higher susceptibility to acute and chronic lung diseases. Individual factors that modulate …
