Malaria
white blood cells
Blood cells with antibodies specific to antigens, which are produced in large quantities to clear the infection
Immune system

Phagocytosis (blood cells ingesting pathogens)
Antibody production
Antitoxin production
Phagocytes engulf and destroy invading microorganisms through phagocytosis.
The immune system produces antibodies that bind to specific antigens on the surface of pathogenic bacteria or viruses, marking them as foreign substances.
White blood cells called lymphocytes produce antibodies that bind to foreign substances such as bacteria or viruses, marking them for destruction by other white blood cells.
