The Lymphatic/Immune System - Coggle Diagram

- - - - Lymph nodes filter out the damaged cells and cancer cells. They also produce and store lymphocytes and other immune system cells that attack and destroy bacteria and other harmful substances in the fluid.
    - - is a network of capillaries and a large network of tubes located throughout the body that transport lymph away from tissues. Lymphatic vessels collect and filter lymph at the nodes as it continues to move toward larger vessels called collecting ducts
- - - - Natural killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils
        
        Dendritic Cells:are antigen-presenting cells aka accessory cells of the mammalian immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system. They act as messengers between the innate and the adaptive immune systems.
        
        Macrophages: are specialized cells involved in the detection, phagocytosis, and destruction of bacteria and other harmful organisms. In addition, they can also present antigens to T cells and initiate inflammation by releasing molecules that activate other cells.
        
        Natural killer Cells: are activated in response to interferons or macrophage-derived cytokines. They serve to contain viral infections while the adaptive immune response generates antigen-specific cytotoxic T cells that can clear the infection
        
        Mast Cells: Known as astrocyte or a labrocyte is a resident cell of connective tissue that contains many granules rich in histamine and heparin. It is a type of granulocyte derived from the myeloid stem cell that is a part of the immune and neuroimmune systems. Mast cells recognize harmful antigens by binding to pathogens directly or associating with PAMPs on the mast cell surface.
      - Independent antigen and First line of Defense
      - Skin, hair, cough, mucous membranes, phagocytes, granulocytes
- - - - T and B lymphocytes
        
        B lymphocytes are the center of the adaptive humoral immune system and are responsible for mediating the production of antigen specific immunoglobulin and directed against invasive pathogens
        
        T lymphocytes play a central role in regulation of antigen-specific immune responses, by modulating the function of antigen-presenting cells
      - Dependent Antigen and Second line of Defense
      - Pus, swelling, redness, pain, T and B lymphocyte response
