Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system. Here are the major pathologic or structural changes associated with cystic fibrosis:

1. Partial airway obstruction leading to hyperinflation: This occurs when the thick, sticky mucus associated with cystic fibrosis clogs the airways. This obstruction prevents the full expulsion of air during exhalation, leading to hyperinflation of the lungs.

2. Bronchospasm: This is a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the irritation and inflammation of the airways from the persistent infection and the thick, sticky mucus.

3. Thick, tenacious mucus: People with cystic fibrosis produce mucus that is thicker and stickier than normal. This mucus can clog the airways and trap bacteria leading to infections, extensive lung damage, and eventually, respiratory failure.

4. Total airway obstruction leading to atelectasis: Atelectasis is the complete or partial collapse of a lung or lobe of a lung. This can occur when the airways are completely blocked by the thick, sticky mucus. This prevents air from reaching the alveoli, causing them to collapse.
