Resin cast of a human lung with a section affected with bronchiectasis. The bronchial tubes have destroyed cilia and this fails to keep material and pathogens from entering the lung and they do not fill properly with air. Normally, the lungs take in around 0.5 liters of air in every breath, with around 12 breaths per minute at rest. The lungs have a large network of airways which gives them a huge surface area for oxygen to diffuse into the blood and carbon dioxide to diffuse out.
