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: -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, the process by which macrophages, dendritic cells and other myeloid phagocytes internalize diverse particulate targets, is a key mechanism of innate immunity. The molecular and cellular events underlying the binding and engulfment of targets in phagosomes have been extensively studied.

Detailed explanation-4: -Macrophages work as innate immune cells through phagocytosis and sterilization of foreign substances such as bacteria, and play a central role in defending the host from infection. However, residual macrophages in intestinal mucosa can potentially reduce inflammation to a greater extent than those in other tissues.

Detailed explanation-5: -phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles.
