Bubonic plague infects which system?

Bubonic plague infects which system?

• A. Circulatory system
• B. Nervous system
• C. Lymphatic system
• D. Digestive system

Answer: (C)

Bubonic plague primarily involves the lymphatic system. After a flea bite introduces Yersinia pestis, the bacteria travel through lymphatic vessels to nearby lymph nodes, causing painful swelling called buboes. This lymphatic infection is the hallmark of the bubonic form. The circulatory system can become involved if the infection spreads into the bloodstream, but the key feature here is the lymphatic involvement. The nervous and digestive systems are not the primary targets of bubonic plague.
