Which of the following does NOT promote elastic recoil of the lungs?
A) elastic fibres in the lung
B) surface tension of the fluid lining the alveoli
C) pulmonary surfactant

Question

Quizplus · Accepted Answer

Pulmonary surfactant actually reduces surface tension in the alveoli, which helps prevent their collapse and promotes lung expansion. Elastic fibres in the lung also help promote lung recoil. Therefore, the only option that does not promote elastic recoil of the lungs is C, pulmonary surfactant.
