Lung Anatomy

Smoking changes the lung’s structure long before symptoms appear. Cilia become paralyzed, mucus builds up, and chronic inflammation narrows the airways. Over time, the alveoli stretch and rupture, reducing the surface area available for gas exchange. The result: air gets in, but it can’t escape efficiently — trapping stale air and straining both lungs and heart. Animation based on the SciePro 3D anatomy model.
