PATHOLOGY

Detailed explanation-1: -Phagocytosis is an important process for nutrition in unicellular organisms, while in multicellular organisms it is found in specialized cells called phagocytes. Phagocytosis consists in recognition and ingestion of particles larger than 0.5 m into a plasma membrane derived vesicle, known as phagosome.

Detailed explanation-2: -phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles.

Detailed explanation-3: -Macrophages and neutrophils recruit neutrophils and monocytes to infectious sites. Neutrophils activate macrophages, and macrophages activate neutrophils. Macrophages and neutrophils cooperate as effectors of antimicrobial innate immunity: Neutrophils and macrophages phagocytose and kill microbial pathogens.

Detailed explanation-4: -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-5: -Macrophages don’t eat cells the same way you might eat your food. Instead, the eating machines engulf viruses and bacteria. This is called phagocytosis. First, the macrophage surrounds the unwanted particle and sucks it in.
