Detailed explanation-1: -Macrophages are specialised cells involved in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In addition, they can also present antigens to T cells and initiate inflammation by releasing molecules (known as cytokines) that activate other cells.

Detailed explanation-2: -Myeloid cells such as neutrophils, macrophages, and dendritic cells play a key role in the innate immune system by recognizing and removing bacteria.

Detailed explanation-3: -Phagocytes (neutrophils and monocytes) are immune cells that play a critical role in both the early and late stages of immune responses. Their main role is to circulate and migrate through tissues to ingest and destroy both microbes and cellular debris.

Detailed explanation-4: -Macrophages are a type of white blood cell that play an integral part in the immune system with the role of phagocytosing foreign antigens, such as bacteria. They are able to present these antigens to other immune cells, such as T-cells, for further destruction.

Detailed explanation-5: -Macrophages have pivotal functions in homeostasis and many physiological processes beyond innate immunity, including metabolic function (7), clearance of cellular debris (8), tissue repair and remodeling (9).
