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.

Of the granulocytes phagocytosis is characteristic of the neutrophil and the?
Neutrophils are the only granulocytes that phagocytize bacteria. (Granuloctyes include neutrophils, eosinophils, and basophils.) Eosinophils do NOT phagocytize (eat); they kill parasidic worms by releasing enzymes and chemicals that create holes in the cells' membranes. Two types of agranulocytes are lymphocytes and monocytes. Monocytes function in phagocytosis. Also, monocytes turn into macrophages in tissues.
What is an organelle?
An organelle is a structure that is found within a cell and serves a specific function.
The function of a cell depends primarily on?
structureThe shape of the protein will determine the cell. It will also determine the function of the cell.
Bones are classified by whether they are weight bearing or protective in function?
False
What is the relationship between structure and function of specialised cell structures?
the cell's structure is based on what kind of function it's supposed to do.
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.
How does our body protect us if the pathogens get into our blood?
Directly through the bacteriophagic function by macrophages, lymphocytes etc and indirectly by immunity
Is the primary function of lymphocytes to circulate oxygen to tissue?
No, the primary function of lymphocytes is to neutralize pathogens.
What is the primary function of the lymphocytes?
Body immunity.
What has the function of immune defense and phagocytosis?
lymphocytes
How can white blood cells destroy microorganisms?
Neutrophils, macrophages and dendritic cells can all phagocytose foreign microorgnamisms.
Functions of lymphocytes?
Lymphocytes have a <protective role>. Particular function depends on the type of lymphocytes. T cells are involved in cell-mediated immunity whereas B cells are primarily responsible for humoral immunity (relating to antibodies). Protective functions are done through: lysis of virually infected cells or tumor cells, realease of cytokines and growth factors to stimulate otherimmune cells, immunoregulation and cytotoxicity, destruction of virally infected cells, secretion of antibodies
What type of cells does HIV attack and destroy?
HIV infects only the CD4 cells of the immune system, and it destroys lymphocytes.
Function of T-Lymphocytes?
T- lymphocytes are the "Generals of the immune system" and direct much of the immune response. Their biggest role is in telling B lymphocytes to make antibodies but they also have other functions.
Which organ has the chief function of production of lymphocytes and plasma cells?
The Spleen
How are antigens removed from bacteria?
Macrophages ( in the lymph nodes ) act like phagocytes to engulf and digest the pathogen. But they do not fully digest it. They separate out the antigens and incorporate them into a cell surface molecule. This is exposed on the surface of the macrophage, which becomes known as an antigen-presenting cell. Its function is to find the lymphocytes that can neutralise that particular antigen.
What is the function of B Lymphocytes?
IMPORTANCE OF B LYMPHOCYTES: 1.b lymphocytes play important role in humeral immune response. 2.they secretes antibodies. 3.they differentiate into memory and plasma cells.
