Question

Macrophages are derived from
A. Neutrophils
B. Lymphocytes
C. Monocytes
D. Basophils

Answer 1

Macrophages are specialised cells which involve functions like detection, phagocytosis and destruction of bacteria and other harmful organisms. They can also present antigens to T cells and initiate inflammation by releasing molecules also known as cytokines that activate other cells.

Complete answer:
Macrophages are immune system white blood cells that engulf and digest anything that does not have proteins specific to healthy body cells on its surface, such as cancer cells, microbes, cellular debris, foreign substances, and so on. The process is known as phagocytosis, and it serves to protect the host from infection and injury.

When there is tissue harm or contamination, the monocytes leave the circulation system and enter the influenced tissue or organ and go through a progression of changes to become macrophages.
In an interaction known as phagocytosis, a macrophage engages in and processes cell trash, unfamiliar substances, organisms, disease cells, and anything else that does not have the type of proteins explicit to sound body cells on its surface. Macrophages are thus derived from Monocytes. Macrophages circulate throughout the body, contributing to both homeostasis and illness.

As of late, it has become obvious that most grown-up tissue macrophages start during early-stage advancement and not from coursing monocytes. Each tissue has its own piece of embryonically determined and grown-up inferred macrophages; however, it is muddled whether macrophages of particular beginnings are practically tradable or have interesting jobs at a consistent state. This new agreement additionally prompts a reevaluation of the capacity of circling monocytes.

Macrophages are professional phagocytes that live in tissues and present antigens (APC).Macrophages develop from monocytes in the blood. They play an important active and regulatory role in both innate and adaptive immunity.

In a process known as phagocytosis, a macrophage engulfs and digests cellular debris, foreign substances, microbes, cancer cells, and anything else that does not have the type of proteins specific to healthy body cells on its surface. As a result, Macrophages are derived from Monocytes. As a result, the correct answer is 'Monocytes.'

Hence correct answer is option (C).

Note: Macrophages separate from coursing blood monocytes. They play out a significant dynamic and administrative capacity in natural just as versatile invulnerability.
