What condition results from alveolar wall deterioration and loss of elasticity in the lungs?

The condition characterized by alveolar wall deterioration and loss of elasticity in the lungs is emphysema. In emphysema, the air sacs, or alveoli, become damaged and start to lose their shape, which decreases the surface area available for gas exchange. The loss of elasticity in the lung tissue impairs the ability of the lungs to fully expand and contract, leading to difficulties in breathing and reduced oxygen intake. This progressive disease is commonly associated with long-term exposure to irritants such as cigarette smoke and environmental pollutants, which contribute to the inflammation and destruction of the alveolar walls. The understanding of emphysema is crucial in the context of chronic obstructive pulmonary disease (COPD), where it plays a significant role alongside chronic bronchitis. Other respiratory conditions listed do not primarily involve the deterioration of alveolar walls or loss of elasticity in the same way that emphysema does.
