GENERAL HISTOLOGY

Detailed explanation-1: -Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. Their name comes from the Greek phagein, “to eat” or “devour", and “-cyte", the suffix in biology denoting “cell", from the Greek kutos, “hollow vessel".

Detailed explanation-2: -Phagocytes surround any pathogens in the blood and engulf them. They are attracted to pathogens and bind to them. The phagocytes membrane surrounds the pathogen and enzymes found inside the cell break down the pathogen in order to destroy it.

Detailed explanation-3: -Macrophages are effector cells of the innate immune system that phagocytose bacteria and secrete both pro-inflammatory and antimicrobial mediators. In addition, macrophages play an important role in eliminating diseased and damaged cells through their programmed cell death.
