lung compliance

Lung compliance refers to how easily the lungs can expand and stretch when you breathe in. It depends on the elasticity of lung tissue and the surface tension within the air sacs. High compliance means the lungs expand readily with little effort, while low compliance indicates they are stiff and harder to inflate. Factors like lung health, age, and diseases (e.g., fibrosis or emphysema) can affect compliance. Essentially, compliance measures the lung’s ability to fill with air during each breath, impacting breathing efficiency.
