What chemical do macrophages secrete?
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.
Which cells produce and secrete antibodies that set up bacterial invaders for subsequent destruction by macrophages?
B Cells
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.
How do macrophages replicate?
Macrophages do not replicate. The bone marrow produces Monocytes which when they find a damaged area transform into Macrophages.
Which organ does NOT contain fixed macrophages?
The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.
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.
Are macrophages responsible for allergic reactions?
No, macrophages are responsible for removing dying or dead cells in the early stages of inflammation. Macrophages essentially ingest these.
What happens to monocytes when they enter tissues?
They become larger and turn into macrophages
What is alveolar macrophages also known as?
Alveolar macrophages, aka DUST CELLS.
What is murine macrophages?
Murine means "of, related to, or affecting rodents of the family Muridae," like mice. Murine macrophages are simply macrophages of these types of animals.
What are immature monocytes?
MACROPHAGES (Some Monocytes enter tissue, enlarge, and Mature into Macrophages).
Some monocytes enter the tissues and mature into phagocytic cells called?
macrophages.
