In order to defend our body, macrophages release chemicals that are toxic to eliminate diseases and harmful foreign bodies. They also secrete growth factors that are essential in healing wounds.

Does a gland secrete Chemical messengers called leucocytes?

No, glands do not secrete leucocytes. Leucocytes, also known as white blood cells, are produced in the bone marrow and play a key role in the immune system by protecting the body against infections and diseases. Glands secrete hormones, enzymes, or other substances that regulate various bodily functions.

Which cells surround and destroy bacteria?

White blood cells, specifically neutrophils and macrophages, are responsible for surrounding and destroying bacteria in the body. Neutrophils can engulf bacteria through a process called phagocytosis, while macrophages can also secrete toxic chemicals to kill bacteria.

Does lymphoid macrophages secrete antibodies into the blood?

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.


Which organ does NOT contain fixed macrophages?

The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.


Skin macrophages that help activate the immune system?

Skin macrophages, primarily represented by Langerhans cells and dermal macrophages, play a crucial role in activating the immune system. They act as antigen-presenting cells, capturing and processing pathogens, then presenting their antigens to T cells to initiate an immune response. Additionally, they secrete cytokines that help recruit and activate other immune cells, thereby enhancing the body's defense against infections and maintaining skin homeostasis. Their presence is vital for both innate and adaptive immunity in the skin.
