In aging there is usually a gradual INCREASE in the compliance of the lung tissue (i.e. a decrease in tissue elasticity). This means that the lung is more easily distended but then has more difficulty in recoiling to it's original state and so exhalation can become difficult. The compliance of the chest wall is decreased in aging, and respiratory muscles weaken, adding to this effect.

What characteristics of normal lung tissue are missing from diseased tissue?
the two main characteristics of normal lung tissue that may be affected in diseased individuals are either Compliance or Elasticity. compliance is the characteristic of lung tissue that allows it to expand elasticity is the characteristic of lung tissue that allows it go back to its former shape and size. elasticity is usually affected in chronic obstructive conditions like emphysema compliance is usually affected in restrictive lung dysfunctions like pulmonary fibrosis.
