The buildup of this mucus clogs ducts and body tubes, leading to chronic tissue inflammation and the replacement of injured cells with scar tissue which blocks the airways of the lungs and ducts in the pancreas and liver. In the lungs, this mucus impairs breathing and causes chronic bacterial infections. Lung disease is the main cause of death from cystic fibrosis. Occlusion of ducts in the pancreas prevents digestive enzymes produced...
