In malarial infection, lysolecithin which destroys RBC is secreted by

Options

A. Liver
B. Plasmodium
C. Spleen
D. WBC

Answer

**Step-by-Step Solution:**

1. **Understanding Malarial Infection**: In malaria, the red blood cells (RBCs) are infected by the Plasmodium parasite, which leads to their destruction.

2. **Identifying the Role of the Spleen**: When RBCs are infected, the spleen plays a crucial role in responding to this infection. It detects the presence of infected RBCs.

3. **Function of Macrophages**: The spleen releases macrophages, which are immune cells responsible for engulfing and destroying infected or damaged cells through a process called phagocytosis.

4. **Role of Lysolecithin**: To enhance the efficiency of phagocytosis, the spleen secretes an enzyme called lysolecithin. This enzyme helps in breaking down the RBCs, particularly those that are no longer functional, often referred to as "ghost RBCs."

5. **Conclusion**: Therefore, in malarial infection, lysolecithin, which destroys RBCs, is secreted by the spleen.

**Final Answer**: Lysolecithin is secreted by the spleen.
