IMMUNOLOGY

Detailed explanation-1: -Phagocytosis consists in recognition and ingestion of particles larger than 0.5 m into a plasma membrane derived vesicle, known as phagosome. Phagocytes can ingest microbial pathogens, but importantly also apoptotic cells.

Detailed explanation-2: -Overview. The chemicals also attract white blood cells that “eat” microorganisms and dead or damaged cells. The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes.

Detailed explanation-3: -Phagocytosis (cell eating) describes the ingestion of large particles such as cell debris and whole microorganisms by means of large vesicles. While all eukaryotic cells are continually ingesting fluid and molecules by pinocytosis, only specialized phagocytic cells ingest large particles.
