What is the primary organ affected by tuberculosis?

• A. Liver
• B. Kidneys
• C. Heart
• D. Lungs

Answer: (D)

The primary organ affected by tuberculosis is the lungs. Tuberculosis (TB) is primarily a respiratory infection caused by the bacterium Mycobacterium tuberculosis, which most commonly attacks the lungs. When a person with active TB coughs, sneezes, or speaks, they can spread the bacteria through the air, leading to the infection of others. While tuberculosis can affect other parts of the body, such as the kidneys, liver, or heart, the lungs are the initial and most frequently involved site. The disease can manifest in other areas, but when tuberculosis is discussed in a general context, the lungs are typically the focus due to the nature of its transmission, symptoms, and diagnosis. This emphasis on the respiratory system is crucial because lung TB can lead to more serious health complications and is more readily identifiable through diagnostic methods like a chest X-ray or sputum test.
