Which of These Statements Does NOT Describe Pulmonary Surfactant

Question

Which of these statements does NOT 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.

Accepted Answer

Pulmonary surfactant lowers the surface tension within the alveoli, allowing for easier expansion and preventing collapse. Therefore, it does not promote elastic recoil of the lungs.
