Lymph nodes: just like how spleen filters

Like the army, navy and air force trained to protect the country from spyware and other countries, various organs of the immune system responsible for protecting the body against parasitic, bacterial, viral, fungal infections and the growth of tumor cells. The immune system consists of organs of the immune system, which in turn consists of several interconnected cells that kill tumor cells and parasitic, destroy viral-infected cells and absorb bacteria. The bodies immune system make cells that contribute to or, in the immune response, or act as sites for the immune system. The main organs of the immune system of the principal organs of the immune system are bone marrow, thymus, spleen and lymph nodes. Let's look at a body and immune system function. Bone marrow: all cells of the human immune system are formed in the bone marrow, found in the bones, in a process called hematopoiesis. The process involves the differentiation of hemopoietic bone marrow stem cells, as in mature immune cells or precursor cells move from bone marrow and continue their maturation lasix 16 mg elsewhere. Bone marrow is responsible for the production of important immune system cells as B cells, granulocytes, natural killer cells and immature thymocytes. It also produces red blood cells and platelets. Thymus: Another site for the production of immune system cells or thymus lymphocytes. This flat, bilobed gland located in the upper chest above the heart and the most actively producing many lymphocytes in childhood days. The main function of thymus is a mature T-cells. Immature cells are produced in the bone marrow, migrate and enter in the thymus, where the process of maturation takes place. This process of maturation great because it allows only useful T cells to be released into the bloodstream. T cells that cause negative autoimmune response to get eliminated. Spleen: This organ of the immune system includes T cells, B cells, natural killer cells, macrophages, dendritic cells and erythrocytes. It acts as an immunological filter blood and captures foreign materials that antigens from the blood passing through the spleen. When macrophages and dendritic cells bring antigens spleen through the blood, B cells in the spleen are activated and produce high levels of antibodies. Thus, the spleen may also be known as a center for conferences immunological. In addition, the spleen also forms the site of an old red blood cell destruction. Lymph nodes: Just like how spleen filters the blood, the lymph nodes filter this fluid between the interstitial cells of the human body. Lymph nodes are located throughout the lymphatic system of the body and nothing but the accumulation of tissue. Lymph nodes are composed mainly of B cells, T cells, macrophages and dendritic cells. They act as an immunological filter and merge lymph to most tissues and filter antigens present in them, before allowing the lymph back into circulation. Other organs of the immune system Adenoids: Adenoids are located in the back of the nasal cavity, where the passage of the nasal cavity meets the throat. They appear as a single cluster of spongy tissue that forms the first line of defense in the body. Their functions are to stop bacteria and other microorganisms to infection infect other body organs. It consists mainly of lymphoid tissue that act as a filter in the body, retards bacteria and viruses. Antibodies present in them help fight infection. In children, this body is very useful, however, decreases with time when the child in the teen and not in adults. Tonsils: There are two masses of soft glandular tissue on the sides of the back of the mouth. They see in the mirror. Along with adenoidami, they also form the first line of defense against infections. Their main function is to trap bacteria and viruses from inhaled air. Lymphocytes and antibodies present in them to help kill bacteria, thus playing an important role in protecting the body. Tonsils reach maturity adolescents and then begin to become less functional. Cells of the immune system now, when we learned about the basic human organs of the immune system, let's look at a variety of immune cells in short. T cells: key features of T-cells and T lymphocytes, enhances the immune response system. They do this, allocating specific factors that in turn activate other white blood cells to fight infection. T cells again divided into several types. One of these units is T-killer cells that plays a role in the killing of some tumor cells and even parasites at times. Natural killer cells: cells act as T-killer cells and cell function-effectors that directly destroy tumor cells and virus infected cells. However, unlike T cells, the natural killer cells do not have to conference in lymphoid organs before killing their targets. B-cells: The main function of these cells is an antibody. They produce antibodies in response to different bacteria, viruses, tumor cells, etc. granulocytes: These cells are 3 types of cells. These neutrophils, eosinophils and basophils, which are defined according to their color. These cells are mainly responsible for removal of parasites and bacteria from the body, the absorption and degrading them. Macrophages: These cells are called scavengers, as they pick up and ingest foreign substances and then present them to T cells and B-cells of the immune system. This step is very important step in initiating the immune response. Dendritic cells: These cells, often in the structural department of the immune system. They absorb antigens and present, if before these bodies to start the immune system. Thus, the antigen is present in cells like dendritic cells and macrophages work together with B cells and T cells of the immune system to initiate the immune response. Antibodies produced against antigens, thereby freeing the body of infection. This system of collaboration between the immune system is just great. .
