Which of the following pulmonary disorders cause the alveolar-capillary membrane thickness to increase?
I.Pulmonary edema
II.Scleroderma
III.ARDS
IV.Pneumonia

Question

Quizplus · Accepted Answer

All of the mentioned pulmonary disorders cause an increase in the thickness of the alveolar-capillary membrane. Pulmonary edema causes an accumulation of fluid in the interstitial spaces between alveoli and capillaries, leading to an increase in the thickness of the membrane. Scleroderma can lead to fibrosis and thickening of the alveolar walls. ARDS is characterized by diffuse alveolar damage, which leads to thickening of the alveolar-capillary membrane. Pneumonia can cause inflammation and fluid accumulation in the alveoli, leading to an increase in membrane thickness.
