Which term describes an infectious disease that may affect almost all tissues of the body, especially the lungs?

• A. Polyp
• B. Tuberculosis
• C. Palliative
• D. Sputum

Answer: (B)

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis that can involve many tissues, with the lungs being the primary site. It spreads through airborne droplets, so it is contagious, and while it commonly affects the lungs, it can disseminate to other tissues as well. The other terms don’t describe an infectious disease: a polyp is simply an abnormal growth; palliative refers to comfort-focused care; sputum is mucus coughed up from the airways, not a disease. Tuberculosis fits the description because it is infectious and can affect almost all tissues, especially the lungs.
