THE LYMPHOID-IMMUNE SYSTEM
  1. IMMUNE SYSTEM
    1. FUNCTIONS
      1. Protect against disease or other pathogens.
        1. Through a series of steps called the immune response, it recognizes and attacks pathogens.
      2. It´s the body's defense against infectious organisms and other invaders. It attacks organisms and substances that invade body systems.
        1. IMMUNITY
          1. Active
            1. Passive
            2. LYMPHATIC SYSTEM
              1. FUNCTIONS
                1. Drain the excess of intersitial fluid from tissue and blood
                  1. Fluid brought by pressure differences between blood vessels and intersitial space. When this fluid enters the lymphatic vessels it is soon called lymph.
                  2. lipid transport
                    1. Lymphatic capillaries in the small intestine known as lacteals absorb dietary lipids.
                    2. Disease resistance
                      1. B cells and macrophages in the lymph nodes and spleen produce antibodies that mark and destroy antigens
                    3. It is a network of vessels that contain and transport lymph
                    4. ORGANS
                      1. Spleen
                        1. Filters the blood. It removes old or damaged red blood cells. It also triggers the release of lymphocites.
                        2. Tonsils
                          1. Help fight infections.
                          2. Appendix
                            1. Releases some mucus into the large intestine.
                            2. Lymph node
                              1. Filters lymph
                              2. Thymus
                                1. Immature lymphocytes first go to its cortex to become T cells, but their maturation finishes in the medulla.
                                2. Bone marrow
                                  1. Production and early selection of lymphocytes.
                                  2. Peyer’s patches
                                    1. Contain mostly B cells.
                                    2. Lymphatic vessels
                                      1. Carry lymph from the body's tissues to the blood vessels and heart.
                                        1. MALT
                                          1. immune cells located diffusely in the digestive, respiratory, or urogenital mucosae
