What do lymph nodes house what in order to remove pathogens from lymph's?
Lymphocytes and macrophages
ARE Macrophages lymphocytes?
The type of leukocyte that becomes a macrophage is a monocyte. Macrophages are cells that digest cellular debris and pathogens.
Stimulate the proliferation of other lymphocytes?
Macrophages stimulate the production of other lymphocytes. They are produced by the differentiation of monocytes in tissues.
What is found in the lymph nodes and tonsils?
Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms. They remove and destroy potentially harmful foreign particles from the lymph through phagocytosis by macrophages. They are also the centers for the production of lymphocytes that act against foreign particles.Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms.
What proteins produced from lymphocytes macrophages and fibroblasts following infection by a virus?
Interferon
What are The cells directly responsible for cellular immunity?
White blood cells, more specifically B-lymphocytes.
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 is the role of macrophages in stimulating B lymphocytes?
some B lymphocytes are taken by macrophages to lymph nodes during the invasion the pathogen. The macrophages the exposes the pathogen's antigens to the B cells in the lymph nodes,The B cells with the matching receptor of the specific antigens respond by dividing repeatedly by mitosis, producing huge numbers over a few weeks.
The bodys most specific defense mechanism is the what?
The adaptive or specific defense mechanisms: lymphocytes, antibodies, and macrophages.
What are the seven types of leukocytes?
The seven types of leukocytes are: neutrophils, eosinophils, basophils, monocytes, macrophages, dendritic cells, and lymphocytes. Neutrophils, basophils, esinophils, monocytes and lymphocytes are the five most commonly thought of.
Are lymphocytes phagocytic?
Yes, the lymphocytes neutrophils, eosinophils, monocytes, macrophages, dendritic cells, and B-lymphocytes. The are the primary method the body uses to remove free microorganisms in blood and tissue fluids.
What white blood cells comprise 3 7 percent of circulating WBC's are phagocytic and can migrate out into body tissues to diffentiate into macrophages?
lymphocites
