2. Gametocytes change to sporozoites and migrate to salivary gland 3. Sporozoites are transferred to human via bite 4. Sporozoites enter liver and reproduce causing the liver cells to burst releasing merozoites 5. Merozoites enter red blood cells and produce schizonts which cause the red blood cells to burst. This makes us feel ill and releases more merozoites and gametocytes. 6. The mosquito ingests gametocytes through bite |
