phagocytosis

Explanation:

Phagocytosis is one of the non-specific immune responses generated by the immune system. Pathogens and microbes release several chemicals that serve to attract the specific cells of the immune system. These cells that perform phagocytosis are called phagocytes. Phagocytes recognize the chemicals released by pathogens and engulf the pathogens to kill them followed by disposal of the dead matter.

For example, neutrophils release intracellular lysozymes that kill certain bacteria, and strong oxidants such as H2O2 that kill the pathogen cells by bleaching them.
