Which term is described by a condition with labored breathing due to enlarged air spaces in the lungs?

• A. Emphysema
• B. Diabetes Mellitus
• C. Endocarditis
• D. Myocardial Infarction

Answer: (A)

Emphysema is a lung condition where the walls of the tiny air sacs (alveoli) are damaged, causing the air spaces to enlarge. This reduces the surface area for gas exchange and traps air in the lungs, so breathing becomes an extra effort and can feel labored, especially with activity. The lungs also lose elastic recoil, making it harder to exhale fully, which adds to the difficulty in breathing. This condition is commonly linked to smoking or a genetic deficiency that protects the lungs. The other options involve blood sugar issues or heart problems and don’t describe enlargement of lung air spaces.
