Which of these statements does NOT correctly describe pulmonary surfactant?
A)It is secreted by Type II alveolar cells.
B)It is deficient in newborn respiratory distress syndrome.
C) It promotes elastic recoil of the lungs.
D) The cohesive force between a water molecule and an adjacent pulmonary surfactant molecule is much lower than the cohesive force between two adjacent water molecules.

Question

Quizplus · Accepted Answer

Pulmonary surfactant reduces surface tension in the alveoli, which makes it easier for them to inflate during inspiration. This results in decreased elastic recoil of the lungs, so statement C is incorrect. The other statements are correct.
