A Level Biology Revision "Neutrophils, Macrophages and Phagocytosis"

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/... 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 antigen-presenting cells. Finally, we look at cytokines. Image credits: Human Skin Structure https://commons.wikimedia.org/wiki/Fi...
