Microfilariae are liberated by female Wuchereria inside

Options

A. Blood
B. Lymph
C. Body cavity
D. Muscles

Answer

**Step-by-Step Solution:**

1. **Understanding the Organism**: The question involves Wuchereria, which is a genus of filarial worms. The most notable species is Wuchereria bancrofti, which causes lymphatic filariasis, commonly known as elephantiasis.

2. **Life Cycle of Wuchereria**: Wuchereria has a complex life cycle that involves two hosts: humans (the definitive host) and mosquitoes (the intermediate host). The female Wuchereria releases microfilariae, which are the larval stage of the parasite.

3. **Microfilariae Release**: The microfilariae are released by the female Wuchereria into the bloodstream of the human host. This release typically occurs in the lymphatic system, specifically in the lymphatic vessels.

4. **Role of Mosquitoes**: The Culex mosquito acts as a vector for the transmission of the microfilariae. When a mosquito bites an infected human, it ingests the microfilariae, which can then develop into the infective larval stage within the mosquito.

5. **Conclusion**: Therefore, the correct answer to the question is that microfilariae are liberated by the female Wuchereria inside the lymphatic vessels of the human host.

**Final Answer**: Microfilariae are liberated by female Wuchereria inside the lymphatic vessels.
