Question

Filaria worm resides in human body in

• A. Subcutaneous tissue
• B. Lymph glands and lymph vessels
• C. Liver
• D. Spleen

Answer 1

The correct option is B Lymph glands and lymph vessels

Lymphatic filariasis is a parasitic disease caused by three species of microscopic, thread-like worms. The adult worms only live in the human lymph system. The lymph system maintains the body’s fluid balance and fights infections. The disease spreads from person to person by mosquito bites. When a mosquito bites a person who has lymphatic filariasis, microscopic worms circulating in the person’s blood enter and infect the mosquito. When the infected mosquito bites another person, the microscopic worms pass from the mosquito through the skin, and travel to the lymph vessels. In the lymph vessels they grow into adults.

So, the correct answer is 'Lymph glands and lymph vessels'.
