Which congenital disease is characterized by mucus buildup in the lungs due to pancreatic failure?

• A. Cystic fibrosis
• B. Pneumonia
• C. Bronchitis
• D. Asthma

Answer: (A)

Cystic fibrosis is a congenital genetic disorder caused by faulty chloride channels, which leads to very thick, sticky mucus in the lungs and also blocks the pancreatic ducts. In the lungs, this mucus clogs airways, promoting recurrent infections and chronic respiratory problems. In the pancreas, the blockage prevents enzymes from reaching the gut, causing pancreatic insufficiency and malabsorption. The combination of mucus buildup in the lungs due to pancreatic failure is the hallmark of this condition. Other options describe infections or reactive airway diseases that aren’t linked to pancreatic insufficiency, so they don’t fit this specific pattern.
