    Pulmonary surfactant, a phospholipid film, reduces surface tension in lung alveoli. This prevents smaller alveoli from collapsing, ensuring respiratory stability.

    Area of Science:

    • Pulmonary physiology
    • Surface chemistry

    Context:

    • The lung alveoli present a biological air-liquid interface.
    • Surface tension forces at this interface can cause alveolar instability.

    Purpose:

    • To explain the physical forces acting on alveolar walls.
    • To identify the mechanism maintaining alveolar stability during respiration.

    Summary:

    • Alveolar walls behave like an air-liquid interface, subject to surface tension.
    • This tension creates pressure, potentially causing smaller alveoli to collapse into larger ones.
    • Phospholipids form a surface film, reducing surface tension and providing necessary "surface-tensio-active" properties for alveolar stability, hence the term "surfactant".

    Impact:

    Related Experiment Videos

  • Understanding surfactant function is crucial for respiratory health.
  • This mechanism explains how lungs maintain structural integrity despite pressure gradients.
