Macrophages are phagocytes, acting in both non-specific defense as well as to help initiate specific defense mechanisms of vertebrate animals. Their role is to phagocytose (engulf and then digest) cellular debris and pathogens either as stationary or mobile cells, and to stimulate lymphocytes and other immune cells to respond to the pathogen.

Which white blood cells turn into macrophages in tissue?
Macrophages are a type of white blood cell that begin their lives as monocytes. monocytes develop into macrophages or dendritic cells. For stem cells, please visit BOC Sciences
Where do macrophages originate in the body?
Macrophages originate from monocytes, which are a type of white blood cell produced in the bone marrow. Once they enter the bloodstream, monocytes can migrate to various tissues and organs where they differentiate into macrophages.
DO Lymphokines attack macrophages?
Lymphokines do not attack macrophages. Lymphokines are molecules released by activated T cells to regulate the immune response, while macrophages are immune cells that engulf and digest pathogens. However, some lymphokines can stimulate macrophages to be more effective in phagocytosis and killing of pathogens.
Red blood cells are called macrophages true or false?
FALSE macrophages are white blood cells that are a part of the immune response system.
Are highly phagocytic cells that are a part of the body's defense system These cells can be localized or they can wander throughout the body?
These cells are called macrophages. They play a key role in engulfing and digesting pathogens and debris in the body. Macrophages reside in specific tissues or circulate in the blood to different parts of the body to carry out their immune functions.
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.
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 is alveolar macrophages also known as?
Alveolar macrophages, aka DUST CELLS.
What happens to monocytes when they enter tissues?
They become larger and turn into macrophages
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.
Some monocytes enter the tissues and mature into phagocytic cells called?
Macrophages
What are immature monocytes?
MACROPHAGES (Some Monocytes enter tissue, enlarge, and Mature into Macrophages).
How does macrophages fight disease?
macrophages engulf, or eat , any microorganisms or viruses that enter your body
Which white blood cells turn into macrophages in tissue?

Why would you not expect to see tissue macrophages in a blood smear?
Tissue macrophages reside in the tissues, not the blood. Tissue macrophages can't be seen because, macrophages as well as neutrophils are the only transient residents of the bloodstream, and more out of the circulation and into the tissues relatively quickly (within a few hours).
Where are macrophages located?
lungs
