Lung growth and aging

Lung elasticity and age

Lung elasticity as a function of age in adultsThe elastic properties of lung and thorax change during growth and aging. In adults the lung becomes gradually more flaccid: the pressure required to inflate the lung to the same volume diminishes. Also the relaxed lung volume, i.e. the volume when transpulmonary pressure is nil, increases. It is to be expected that residual volume will comprise a larger part of the total lung capacity, and that hence the vital capacity declines.
