Mr.Schmitzer has pulmonary fibrosis in which the elastic tissue of his lungs is replaced with dense irregular collagenous connective tissue.His condition primarily affects:
A)surfactant production.
B)alveolar surface tension.
C)pulmonary compliance.
D)airway resistance.

Question

Quizplus · Accepted Answer

Pulmonary fibrosis leads to a reduction in lung compliance, or the ability of the lungs to expand and contract easily. The replacement of elastic tissue with collagenous connective tissue makes the lungs stiff and difficult to inflate, reducing the efficiency of gas exchange in the alveoli. This can cause shortness of breath and difficulty breathing. Surfactant production, alveolar surface tension, and airway resistance may be affected in other lung diseases, but they are not the primary mechanisms affected in pulmonary fibrosis.
