In this video, we look at neutrophils, macrophages and phagocytosis. First we explore the different categories of white blood cells. We then look at how neutrophils carry out phagocytosis and the role of opsonins. Then, we explore the role of macrophages as antigenpresenting cells. Finally, we look at cytokines.
