  12. reticul/o
    a net
  13. splen/o
    spleen
  14. thromb/o
    clot
  15. thym/o
    thymus gland
  16. plasma
    liquid portion of the blood and lymph; contains water, proteins, and cellular components
  17. serum
    liquid portion of the blood that remains after clotting
  18. erythrocyte
    red blood cell; transports oxygen and carbon dioxide
  19. hemoglobin
    the protein-iron compound in RBC that transports oxygen and carbon dioxide
  20. leukocyte
    white blood cell; protects the body from harmful invading substances
  21. granulocytes
    a group of leukocytes containing granules in their cytoplasm
  22. neutrophil
    a granular leukocyte, named for the neutral stain of its granules, that fights infection by swalling bacteria (phagocytosis) (neutr = neither, phil = attraction for)
  23. polymorphonuclear (PMN) leukocyte
    another term for neutrophil, referring to many segments in its nucleus
  24. eosinophil
    a granular leukocyte, named for the rose colored stain of its granules, that increase in allergic and some infections reactions
  25. basophil
    a granular leukocyte, named for the dark stain of its granules, that brings anticoagulant substances to inflamed tissues
  26. agranulocytes
    a group of leukocytes without granules in their nuclei
  27. lymphocyte
    an agranulocytic leukocyte that is active in the process of immunity; the three categories of lymphocytes are T cells (thymus dependent), B cell (bone marrow derived), and natural killer (NK) cells
  28. monocyte
    an agranulocytic leukocyte that performs phagocytosis to fight infection
  29. platelets
    thrombocytes; cell fragments in the blood that are essential for blood clotting (coagulation)
  30. thymus
    primary gland of the lymphatic system, located within the mediastinum, that helps to maintain the bodys immune response by producing T lymphocytes
  31. spleen
    organ between the stomach and the diaphragm that filters out aging blood cells, removes cellular debris by performing phagocytosis, and provides an environment for lymphocytes to initiate immune responses
  32. lymph
    fluid that is circulated through the lymph vessels
  33. lymph capillaries
    microscopic vessels that draw lymph from tissues to the lymph vessels
  34. lymph vessels
    vessels that receive lymph from the lymph capillaries and circulate it to the lymph nodes
  35. lacteals
    specialized lymph vessels in the small intestine that absorb fat into the bloodstream
  36. chyle
    white or pale yellow substance in lymph that contains fatty substances absorbed by the lacteals
  37. lymph nodes
    many small, oval structures that filter lymph from the lymph vessels; major locations include cervical, axillary, and inguinal regions
  38. lymph ducts
    collecting channels that carry lymph from the lymph nodes to the veins
  39. right lymphatic duct
    receives lymph from the right upper part of the body
  40. thoracic duct
    receives lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities
  41. immunity
    process of disease protection induced by exposure to an antigen
  42. antigen
    a substance that, when introduced into the body, causes the formation of antibodies against it
  43. antibody
    a substance produced by the body that destroys or inactivates an antigen that has entered the body
  44. active immunity
    a long lasting immunity that results from stimulating the body to produce its own antibodies; developed either naturally, in response to an infection, or artificially, in response to the administration of a vaccine
  45. passive immunity
    a short lasting immunity that results from foreign antibodies that are conveyed either naturally, through the placenta to fetus, or artificially, by injection of a serum containing antibodies
