Pulmonary elasticity
WebStructural changes occur in the respiratory system with advancing age. Lung elasticity decreases, stiffness of the chest wall increases, and respiratory muscle strength declines. … WebLung disease can affect respiratory function, or the ability to breathe, and pulmonary function, which is how well lungs work. There are many different lung diseases, some of which are caused by bacterial, viral, or fungal infections. Other lung diseases are associated with environmental factors, including asthma, mesothelioma, and lung cancer.
