How white blood cell impart Immunity Phagocytosis Video
White blood cells protect our boby from external infection like bacterial fungal or viral.
To achieve this altimate goal white blood cells carry out very complex functions like.
1.Secretion of antibodies
2.Creating Memory of infection and disease causing agents cancerous cells for secretion of Antibodies against them and for neutralization of these infections agents and foreign particles cancerous cells.
