MICROANATOMY

Detailed explanation-1: -Professional phagocytes [2] include monocytes, macrophages, neutrophils, dendritic cells, osteoclasts, and eosinophils. These cells are in charge of eliminating microorganisms and of presenting them to cells of the adaptive immune system.

Detailed explanation-2: -Phagocytes such as neutrophils, macrophages, and dendritic cells make a bridge between specific bacterial surface antigens and cellular receptors. Following this bridge, membrane protrusions surround the bacteria and absorb the bacteria into the phagosome, which is formed by the fusion of cell membranes [9].

Detailed explanation-3: -Professional phagocytes play a central role in innate immunity by eliminating pathogenic bacteria, fungi and malignant cells, and contribute to adaptive immunity by presenting antigens to lymphocytes.

Detailed explanation-4: -Monocytes, macrophages, and neutrophils are phagocytes. A phagocyte is a type of white blood cell.
