Which term describes a genetic disorder present at birth affecting respiratory and digestive systems?

• A. Cystic fibrosis
• B. Wheeze
• C. Emphysema
• D. Influenza

Answer: (A)

The main idea is a congenital genetic disorder that affects both the lungs and the digestive system. Cystic fibrosis fits this description because it’s caused by mutations in the CFTR gene and is present from birth. The defective CFTR protein leads to thick, sticky mucus that clogs airways, causing respiratory problems, and also obstructs the ducts in the pancreas, leading to digestive difficulties and malabsorption. This combination of early onset respiratory issues and digestive involvement is what makes cystic fibrosis the correct term. Wheeze is a symptom of airway narrowing, not a disease present at birth. Emphysema is a chronic lung condition typically associated with smoking and aging, not a congenital genetic disorder. Influenza is an acute viral infection, not a genetic disorder present at birth.
