What is the function of NK cells?
they act as macrophages and eat invaders nearby. it klls anything that is harmful.
What do macrophages arise from?
Monocytes. When monocytes enter the tissue they are called Macrophages.
Which type of cell are big eater?
macrophages
Does the spleen contain numerous macrophages?
Yes
What are bacteria within the buboes attacked by?
Macrophages
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.
Macrophages are attracted to the infected site and are prepared to attack the invaders by what?
Lymphokines
What type of cell movesto infection sites where they ingest and digest infectious microorganisms?
macrophages
Neutrophils and macrophages are capable of ingesting bacteria?
Neutrophils and macrophages attack and destroy bacteria. Neutrophils are mature cells that can ingest bacteria. Macrophages enter tissues and swell ingesting bacteria that is in the tissues and blood stream.
What is the function of NK cells?
they act as macrophages and eat invaders nearby. it klls anything that is harmful.
A cell that engulfs another cell?
Phagocytes ingest and destroy foreign matter or microorganisms.
Which cells produce and secrete antibodies that set up bacterial invaders for subsequent destruction by macrophages?
B Cells
Do Phagocytic cells ingest pathogens and cellular debris?
The phagocyte that digests cellular debris and pathogens in the human body are called macrophages, or macrophagocytes.
Macrophage is a part of the non-specific immune system what does it do?
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.
How does the structure of a lymph node allow lymphocytes and macrophages to perform their protective function?
Macrophages ingest microorganisms and cellular debris. Lymphocytes monitor the lymphatic stream for the presence of antigens and mount an immune response. Because there are fewer efferent vessels draining the node than afferent vessels that feed it, the flow of lymph through the node stagnates somewhat, allowing time for the lymphocytes and macrophages to work.
What do macrophages do?
The macrophages are defense cells that help to protect the body from debris and invaders. They stay among the white blood cells
Are Macrophages and Dendritic cell the same?
Both macrophages and dendritic cells are formed from the same precursor cell, the monocytes. However, the two cells serve different functions during an infection. Macrophages remain in the area of the infection and phagocytosis (engulf) foreign invaders and dead cells. Dendritic cells leave the infected tissue and travel to local lymph tissue in order to alert the adaptive immune system.
