Explanation

Sporozoites are the form of Plasmodium that is transmitted to humans through the bite of an infected female Anopheles mosquito. When the mosquito feeds on an infected human, it ingests the sexual forms of the parasite, which then develop into sporozoites within the mosquito's salivary glands. Sporozoites are injected into the human bloodstream during a mosquito bite and travel to the liver, where they infect liver cells to initiate the liver stage of the malaria life cycle.
