Summary Introduction
Introduction:
The immune system of the vertebrates gives protection against the infectious foreign substances or pathogenic organisms. It is a complex biological reaction which involves in the specific and nonspecific defense against the infectious agents. The pathogenic damages to the defense cells indicate the sign of inflammation. After inflammation, the phagocytic cells are initiated to destroy the invading microbes.
The phagocytosis is a series of process in which the contact of the microbes on surface of the phagocytic cell involves in the chemotactic adherence, ingestion and digestion process.
