Efficient breathing depends not just on airflow, but on the stability of alveoli.
Surface tension within alveoli tends to cause collapse, but pulmonary surfactant reduces this force, allowing alveoli to remain open and function effectively during respiration. This mechanism is essential for maintaining proper gas exchange and lung compliance.
Understanding surfactant function connects basic physiology with real clinical conditions affecting respiratory function.
