PATHOLOGY

Detailed explanation-1: -A macrophage is a large phagocytic cell that engulfs foreign particles and pathogens.

Detailed explanation-2: -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-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.

Detailed explanation-4: -Neutrophils are phagocytes, meaning that they engulf and destroy pathogens or damaged cells; being the most abundant type of immune cell in the blood, they play a key role in the innate immune response against many different types of infection.

Detailed explanation-5: -Macrophages are large white blood cells that reside in tissues that specialize in engulfing and digesting cellular debris, pathogens and other foreign substances in the body.
