There's a lot we don't currently know about lymphoid (ED3) Macrophages but it's relatively safe to assume that they do not have any major role in secreting antibodies.

Macrophages tend to engulf and enzymatically destroy foreign objects in the body, this is their major purpose, if that object is coated in antibodies they're better at destroying it but they do not produce those antibodies themselves.

The only real way that macrophages affect antibody production is that after destruction of intruder they'll present elements of the intruder to another variety of immune cell which will then go on to produce antibodies, it's also possible that they will produce interleukins or other compounds to upregulate antibody production but again: macrophages are not known to produce antibodies.

What is the largest structure in the lymphoid system?

The largest structure in the lymphoid system is the spleen. It is responsible for filtering blood, storing blood cells, and producing antibodies to help fight infection.

Phagocytosis is best associated with what type of blood cells?

Monocytes and macrophages are good example of blood cells which cause phagocytosis. They originate from lymphoid stem cells

What is secondary lymphoid tissue?

Secondary lymphoid organs and tissues are the sites where lymphocytes are most active. The white pulp of the spleen is the common site for plasma cells to develop. Macrophages are also active in the spleen red pulp; where they engulf blood-borne antigens to be presented to T lymphocytes in the circulation.

The cells known as lymphocytes?

secrete antibodies into blood and lymph fluids

What is the largest lymphoid structure located in upper left quadrant of abdomen?

The largest lymphoid structure located in the upper left quadrant of the abdomen is the spleen. It plays important roles in filtering blood, storing red blood cells, and helping the immune system by producing antibodies and removing old or damaged cells from circulation.

What type of cells produce antibodies to destroy pathogens?

B lymphocytes, a type of white blood cell, are responsible for producing antibodies. These antibodies bind to specific pathogens, like bacteria or viruses, marking them for destruction by the immune system.

What lymphoid organs is found along the left side of the abdominal cavity?

The spleen is the primary lymphoid organ located along the left side of the abdominal cavity. It filters blood, stores blood cells, and plays a role in the immune response by producing antibodies and removing old or damaged red blood cells.

What type of white blood cells make antibodies?

There are two types of white blood cell. The kind which secrete antibodies to kill microbes are called lymphocytes. The other type, which engulf microorganisms, are called phagocytes.*Specifically, the type of lymphocyte (white blood cell) that produces antibodies would be plasma cells. After a B cell (a type of lymphocyte) undergoes clonal selection, the result is the formation of a clone of B cells that consists of plasma cells and memory B cells. Plasma cells secrete antibodies and memory B cells do not secrete antibodies.

What is lymphocyte?

The lymphocyte is the main cell of the lymphoid tissue.Lymphocytes are a type of white blood cell which produce antibodies to kill any pathogens which invade the body.They are small white blood cells which have large nuclei, but no granules.They produce antibodies that fight disease and harmful microbes in the body or mark the disease for the phagocytes to engulf.

How do your white blood cells disarm foreign bacteria?

The WBC's (White Blood Cells) enter the area with the bacteria. When the reach, they give off antibodies, which then go and attach to the bacteria. This stops the bacteria. Then the macrophages, or the largest WBC's devour the bacteria along with the antibodies. A chemical in the macrophage causes the bacteria to dissolve.

What type of cell ingests bacteria?

White blood cells can pass through the walls of the capillaries by ameboid movement and migrate to almost any tissue in the body

Red blood cells are called macrophages true or false?

False. Red blood cells are not called macrophages. Macrophages are a type of white blood cell that helps to recognize, engulf, and destroy pathogens and foreign substances in the body.
