Which of the following promotes elastic recoil of the lungs?
A)Elastic fibers in the lung
B)Surface tension of the fluid lining the alveoli
C)Pulmonary surfactant
D)Both a and b
E)All of the above

Question

Quizplus · Accepted Answer

Elastic fibers in the lung and surface tension of the fluid lining the alveoli both contribute to elastic recoil of the lungs. Pulmonary surfactant actually reduces surface tension, which can help prevent atelectasis and improve lung compliance, but it does not directly promote elastic recoil.
