Lymphatic System and Immunity
  1. recirculates interstitial fluid
    1. Components of Lymphatic System
      1. Lymphatic Capillaries
        1. Lymphatic Vessels
          1. Lymph Nodes
            1. Lymphatic Trunks
              1. Lymphatic Ducts
                1. Primary Lymph Organs
                  1. Thymus - T-Cells are formed

                    Annotations:

                    • what is inveloom?
                    • The thymus is where t and b cells mature
                    1. Hangs over heart, largest at puberty, shrinks as we age, makes t-cells, immunocompitent
                    2. Red Bone Marrow - B- cells
                    3. Secondary Lymph Organs and Tissues
                      1. Spleen

                        Annotations:

                        • holds platelets- w/o spleen clotting can become problematic
                        1. White and red pulp; platelets are stored here; white-lymphatic tissue; old rbc's are destroyed here
                        2. Lymph Nodes
                          1. Scattered along lymphatic vessels; superficial and deep; serve as filters
                      2. Lymph- Clear, Milky interstitial Fluid in the lymphatic system
                        1. lymph moves the same way that blood moves-body facilitation

                          Annotations:

                          • lymph fluid moves by respitory pump
                          1. Afferent Vessels- going in

                            Annotations:

                            • There are more Afferent vessels then efferent, this is to give the B and T cells a chance to attack.
                            1. Efferent Vessels - going out

                              Annotations:

                              • Less of these, and they leave the lymph node through the hilum (indentation)
                              1. Immune Response
                                1. Innate

                                  Annotations:

                                  • We are born with this type of immunity, we get this from Mom
                                  • At birth we have non-specific and non adaptive immunity (immune response), this includes 1st and 2nd line of defense pgs 886-888 in text
                                  1. Adaptive (aquired)

                                    Annotations:

                                    • two types, cell mediated or antibody mediated, both are gained through vaccines
                                    • Describes the ability of the body to adapt defenses against antigens of specific bacteria, viruses, foreign tissue.....even toxins
                                    1. Cell mediated
                                      1. Antibody Mediated
                                    2. right side is lymphatic; left side is thoracic

                                      Annotations:

                                      • the sides of the lymphatic system
                                      1. Lacteals

                                        Annotations:

                                        • Specialized lymphatic capillaries
                                        1. chemotaxis

                                          Annotations:

                                          • wandering macrophages
                                          1. Natural Killer Cells

                                            Annotations:

                                            • "Terminator" cells - goes after cancer cells without hesitation - the theory is that we are born with only so many
                                            1. Interferons

                                              Annotations:

                                              • The beta ones are used to treat and to slow the progress of MS
                                              1. Phagocytosis

                                                Annotations:

                                                • There are 5 steps: Chemotaxis, Adherence, Ingestion, Digestion, Killing
