(A) In normal individuals, total lung capacity (TLC) is determined (i.e. limited) primarily by the elastic recoil of the lung .

(B) The elastic recoil of the lung is less than normal in patients with idiopathic pulmonary fibrosis.

(C) The elastic recoil of the lung is less than normal in patients with emphysema.

(D) Increased elastic recoil leads to diminished expiratory flow.
