What is the mode of entry for pathogens causing malaria in human body?

Options

A. Through air
B. Through food
C. Through insects
D. Through animals

Answer

### Step-by-Step Solution:

1. **Identify the Pathogen**: The pathogen responsible for malaria is a protozoan known as *Plasmodium*.

2. **Understand the Transmission**: Malaria is transmitted through a specific vector. In this case, the vector is the female *Anopheles* mosquito.

3. **Mode of Entry**: The *Anopheles* mosquito bites a human and injects the *Plasmodium* parasites into the bloodstream. This is the primary mode of entry for the pathogens causing malaria.

4. **Effects of Infection**: Once inside the human body, the *Plasmodium* parasites initially multiply in the liver cells before attacking red blood cells, leading to symptoms such as chills and high fever due to the rupture of red blood cells.

5. **Conclusion**: Therefore, the mode of entry for the pathogens causing malaria in the human body is through the bite of the female *Anopheles* mosquito.

### Final Answer:
The mode of entry for pathogens causing malaria in the human body is through the bite of the female *Anopheles* mosquito.
