Detailed explanation-1: -Opsonization is an immune process which uses opsonins to tag foreign pathogens for elimination by phagocytes. Without an opsonin, such as an antibody, the negatively-charged cell walls of the pathogen and phagocyte repel each other.
Detailed explanation-2: -Macrophages work as innate immune cells through phagocytosis and sterilization of foreign substances such as bacteria, and play a central role in defending the host from infection.
Detailed explanation-3: -Opsonization is defined as the coating of pathogens with antibodies in order to increase their susceptibility to ingestion by phagocytes.
Detailed explanation-4: -Chemotaxis-the chemical attraction of phagocytes to a particular location; chemotactic chemicals that attract phagocytes include bacterial toxins components of damaged tissue cells, complement proteins, & antibodies.
