Phagolysosome is a cytoplasmic body which is formed by the fusion of the phagosome with lysosome during the process antigen-antibody reaction.
This cytoplasmic body is formed by the fusion of phagosomes and lysosomes in a process which occurs during the time of phagocytosis.
This process occurs when the antigen presenting cells binds to the antigen and kills it.
