What is the difference between phagocytes and lymphocytes?
Fagocytes and lymphocytes come from bone marrow like white blood cells and form a natural immune system of the body, but phagocytes include a larger group of cell types than lymphocytes. Fagocytic cells include granulocytes, macrophages and dendritic cells, while the lymphocyte population consists of B-cells, T-cells and natural killer cells. They can all interact in the presence of infections caused by bacteria, mushrooms or viruses. These defense of the immune system also respond in the presence of cancer growth. Fagocytes generally defend the body by hunting, attacking and consuming cells. When the perceived threat occurs, the phagocytes arrive on the scene, encapsulate the attacker and consume antigen or cell. Fagocytes continue this process until they die. Hus produced by infection usually contains a large number of dead phagocytes.
neutrophils are types of Fagokukuchytic granular lymphocytes. Under the microscope it seems that neutrophils have small spots or granules that contain enzymes that are released as signals to jinch of immune cells, and arrive in large numbers. They also contain a multi-world core. These phagocytes often appear first at the site of infection.
macrophages respond to threats more slowly, are larger and last longer. In addition to having the ability to consume attackers, these cells can then carry the remains of threats for lymphocytes that perform different tasks. Macrophages can also alert the immune system of the problem. Dendritic cells have phagocytic properties, but to a large extent remain in the specific areas of the body, they resemble guards.
After ripening in the bone marrow Lymphocyes usually circulate in organs and vascular structures of the lymphatic system. The spleen, thymus and almonds contain these cells. The lymphatic blood vessels also do.
B-cells are a type of lymphocytes that have the ability to consume attacking threats. These agranular cells usually bind to antigens in the formation of lock and key type. TIf they have the ability to remember specific antigens.
T-cell or auxiliary cell T is another type of lymphocytes. After leaving the bone marrow, these cells generally migrate to the thymus. CD8+ T-cells have cytotoxic properties. When viruses attack, they usually attack cells, hide from the immune response and cheat cells into reproduction by viral deoxyribonucleic acid (DNA). The host cell responds to this attack by exposing proteins on its surface, which attracts CD8+ cells. CD8+ cells then destroy the host cell and its content before replication is set.
CD4+ cells are another type of T-cells. After consuming the attacking cell, this lymphocyte represents antigen into another immune cell. This cell releases chemicals requiring reinforcement that surrounds the CD4+cell, the initiation of symptoms commonly associated with infection. CD4+ T-cells also make answers mediated by antibody. Once B-cells emit chemical signals for T-cell reaction, this cell binds to antigen, allowingB-cells to produce clones excluding antibody.
natural killer cells are variations of lymphocytes. When they take place on infected cells, killer cells inject hosts with toxic enzymes. They also signal the need for increased production of B-cells and T-cells.
