They are used in the first (primary) line of the immune response. These are NOT SPECIALIZED phagocytes, as you can tell, carry out their function via phagocytosis. They engulf bacteria in various ways, but usually just grab the bacteria, engulf it, let it die, and then they die. Helper T and Antibodies mark viruses and bacteria that get past these for destruction. The macrophages recognize the bacteria, and engulf them. Their primary role is to engulf bacteria. They are non-specific.
Macrophages attack foreign substances like toxins, bacteria, and viruses in the blood and tissue of the body by wrapping around and digesting them. They are small white blood cells that are part of the immune system.
Macrophages are white blood cells that locate and phagocytize (eat) bacteria, viruses and dead or injured body cells. They also play a role in alerting the rest of the immune system to the presence of invaders. Macrophages arise from monocytes which are a type of white blood cells. When the monocytes leave the blood they become macrophages.

FALSE macrophages are white blood cells that are a part of the immune response system.
1. Macrophages, T cells, and B cells.
Macrophages are a necessary part of the immune system, so a person who did not have any would suffer from severe immune deficiency and would succumb to opportunistic infection very readily.
The macrophages the T-cells and the B-cells
The innate immunes system does not produce any antibodies. Cells of the innate immune system are macrophages, granulocytes (neutrophils, basophils, eusinophils), natural killer cells...

The structure or organ that plays a role in the immune system as well as the endocrine system is the thymus. The thymus also plays a role in the lymphatic system.
