  1. Vocab:
    • Axillary nodes-filters lymph from arms and legs
    • thoracic trunk-all the major lymph vessels drain into it
    • intestinal trunk-drains lymph from abdomen
    • jugular trunk-drains lymph from head and neck
    • cysterea chyli-drains lymph from thoracic cavity
    • cervical nodes-filters lymph from head and neck
    • lower intercostal trunk-drains lymph from thoracic & abdominal
    • subclavian trunk-drains lymph form arms and shoulders
    • vessels from pelivis and legs-drains lymph into lumbar trunk
    • bronchonediastinal trunk-drains lymph from thoracic cavity
    • inguinal nodes-filters lymph from abdomen and legs
    • lumbar trunk-drains lymph from legs and pelvis
    • tonsils-several small nodes in the phariynx region
    • spleen-destroys worn out TBCs through phagocytosis
    • immune system-specific defense mechanisms of the body
    • lymph-the fluid in the lymphatic vessels
    • thymus gland-stimulates lymphocyte production...
    • lymphatis system-transports lymph through vessels and nodes
    • fixed phagocytic cells-stationary macrophages
    • lymph vessels-transport lymph, similar to vein
    • infection-invaded by a pathogen
    • macrophage-large cells which ingest foreign substance
    • lymph nodes-filter and destroy foreign substances
    • pathogen-any organism that causes a disease
    • lymph capillary-microscopic vessels which receive lymph
    • fever-elevated body temperature due to infection
    • antibody-proteins which eliminate antigens
    • immunity-reactions to pathogens by...
    • cell medistend immunity-immunity accomplished by T cells
    • antigen-foreign substance to which the body responds to
    • B cell-specialized lymphoctes within the spleen
    • humeral immunity-immunity to disease involving antibodies
    • passive immunity-immunity given by another
    • tissue rejection-active immunity against a transplanted organ
    • Helper T cell-the T lymphocyte that orchestrates cellular immunity
    • Memory T cell-cloned to provide immunological memory
    • vaccine-a weakened pathogen to stimulate immunity
    • Killer T cell-lyses foreign cells or cancer cells
    • allergen0active immunity against non pathogens
    • Suppressor T cell-stops other T cells and returns the body to normal
    • allergen-the substance that triggers an allergic response
    • active immunity-manufacturing ones own T cells or antibodies
    • serum-blood plasma from another...
  2. Short Answer:
    • Hodgkins Disease-cancer of the lymph nodes
    • Mononucleosis-abnormally high amount of monocytes
    • Tonsillitis-inflammation of the tonsils
    • Aids-Aquired Immune Deficiency Syndroms: HIV virus, attacks Helper T cells, destroying active immunity
    • Fixed phagocytic cells:stationary macrophages
    • free phagocytic cells-macrophages travel throughout the blood
    • Humoral Immunity-immunity to discus involving antibodies, which is preformed by Bcells
    • Cell Mediated Immunity-immunity accomplishhed by activated T cells,which lyse infected or cancerous body cells and releases chemicals which regulate immune response
  3. Macrophages defend body against disease:
    they engulf, digest, and consume pathogens
  4. Lymph nodes swell with infection:
    to make more lymph and to flush the spent macrophages from the nodes
  5. infected areas become feverish:
    Higher temperatures make a tissue envirorment less fevorable for most pathogenic organisms. It also enables the chemical reactions of the immune system to take place more rapidly.
  6. lymph get into lymph vessels:
    the fluid pressure between the cells is greater than the fluid pressure within the lymph vessels, and this forces the lymph into the lymph vessels
  7. Lymph back into blood:
    lymph vessels drain into the thoracic duct then into the subclavian vein
  8. Body respond to antigen:
    By making chemicals or specialized cells which directly or indirectly eliminate an antigen
  9. T cells and B cells:
    they both search for and eliminate antigens
  10. memory B cells and memory T cells:
    The both result in having the disease and they both eliminate antigens
  11. Active Immunity:
    Have the immunity or get a vaccine
  12. Passive Immunity:
    immunity can be aquired through both natural or artificial means. Natural, antibodies from moms milk. Artificial, antibodies from another persons blood serum. Antibodies being given to that person
