Lung compliance refers to the ease with which the lungs can expand during breathing, influenced by the elasticity of lung tissue and surface tension within the alveoli. High compliance indicates easy expansion, while low compliance suggests stiffness or resistance, impacting respiratory efficiency and requiring more effort for ventilation.

Respiratory efficiency refers to the effectiveness with which the respiratory system exchanges gases, particularly oxygen and carbon dioxide, during the process of breathing. It is influenced by factors such as lung capacity, ventilation-perfusion ratio, and the diffusion capacity of the alveolar-capillary membrane.
