Explanation:
Detailed explanation-1: -Macrophages and neutrophils (phagocytes) are the front-line defenders in your body’s immune system. They seek out, ingest, and destroy pathogens and other debris through a process called phagocytosis.
Detailed explanation-2: -Phagocytosis is a fascinating process whereby a cell surrounds and engulfs particles such as bacteria and dead cells.
Detailed explanation-3: -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.
