Such antibodies are of great importance in establishing immunity to diseases.

Phagocytes adhere to the opsonins, and phagocytosis follows. The nonspecific immunological responses are composed of four basic types of barriers--anatomic, physiologic. Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. Encapsulated bacteria are ingested with more difficulty. The speed with which a phagocytic cell ingests a particle varies somewhat with the size of the particle. Larger objects, such as clumps of bacteria or tissue cells, are phagocytosed over the course of a more-prolonged response.
