The threadlike structures called sporozoites are transmitted into the new host simultaneously. The meorozoite enter the bloodstream and penetrate red blood cell and begin feeding on the hemoglobin for two to four weeks. Hemoglobin is a chemical that transport oxygen. At this point, the symptoms occur in the victim. The meorozoites multiply within the blood cells, produce more meorizoites plus a smaller number of new sporozoites.
Blood cells burst releasing new meorozoites, each one entering a new blood cell.
If another mosquito comes along at this point and bites the victims, the mosquito will suck up the new gametocytes that were released into the blood, and the process recycles to sexually active meorozoites meet in the mosquito gut producing new generation.
