Describe the stages of phagocytosis (4 marks)

Phagocytes (white blood cells) recognise pathogens via receptors and chemoattractionPhagocytes engulf the pathogen, forming an intracellular compartment called a phagosomeLysosomes fuse with the phagosome to form a phagolysosome. Lysozymes contain digestive enzymes called lysozyme that destroy the pathogen. Antigen presentation: The phagocyte will present the pathogen's antigens on the cell surface to further activate the immune system
Extra notes:Phagocytosis is the process where a phagocyte engulfs other cells or particles. This is useful in removing pathogenic material from the body. Phagocytes are white blood cells e.g. neutrophils, macrophages, dendritic cells
