GENERAL HISTOLOGY

Detailed explanation-1: -In addition, macrophages play an important role in eliminating diseased and damaged cells through their programmed cell death. Generally, macrophages ingest and degrade dead cells, debris, tumor cells, and foreign materials.

Detailed explanation-2: -macrophage, type of white blood cell that helps eliminate foreign substances by engulfing foreign materials and initiating an immune response. Macrophages are constituents of the reticuloendothelial system (or mononuclear phagocyte system) and occur in almost all tissues of the body.

Detailed explanation-3: -T cells are direct fighters of foreign invaders and also produced cytokines, which are biological substances that help activate other parts of the immune system. One such part is called macrophages. These macrophages act to clean up the invaders and the dead tissue after an immune response.

Detailed explanation-4: -The specific function of M1 macrophages is to detect, engulf and destroy bacteria. They can do this through phagocytosis, which is a process by which a bridge is formed between cellular receptors on the macrophage and surface antigens on the bacteria.
