#blood_cell__bloodcell__blood_corpuscle__bloodcorpuscle__corpuscle  either of two types of cells (erythrocytes and leukocytes) and sometimes including platelets
  supertype:  somatic_cell__somaticcell  any of the cells of a plant or animal except the reproductive cells
  part of:  blood
  subtype:  leukocyte__leucocyte__whitebloodcell__white_cell__whitecell__white_blood_corpuscle__whitebloodcorpuscle__white_corpuscle__whitecorpuscle__WBC  blood cells that engulf and digest bacteria and fungi; an important part of the body's defense system
     subtype:  myelocyte  an immature leukocyte normally found in bone marrow
     subtype:  myeloblast  a precursor of leukocytes that normally occurs only in bone marrow
     subtype:  lymphocyte__lymph_cell__lymphcell  an agranulocytic leukocyte that normally makes up a quarter of the white blood cell count but increases in the presence of infection
        subtype:  B_cell__B_lymphocyte  a lymphocyte derived from bone marrow that provides humoral immunity; it recognizes free antigen molecules in solution and mature into plasma cells that secrete immunoglobulin (antibodies) that inactivate the antigens
        subtype:  T_cell__T_lymphocyte  a small lymphocyte developed in the thymus; it orchestrates the immune system's response to infected or malignant cells
           subtype:  helper_T_cell__CD4_T_cell__CD4_cell  T cell with CD4 receptor that recognizes antigens on the surface of a virus-infected cell and secretes lymphokines that stimulate B cells and killer T cells
           subtype:  killer_T_cell__CD8_T_cell__CD8_cell  T cell with CD8 receptor that recognizes antigens on the surface of a virus-infected cell and binds to the infected cell and kill it
        subtype:  lymphoblast  an immature lymphocyte
        subtype:  plasma_cell__plasmacyte  a lymphocyte-like cell that develops from a B lymphocyte in reaction to a specific antigen; found in bone marrow and sometimes in the blood
           subtype:  plasmablast  the precursor of a plasma cell
     subtype:  granulocyte  a leukocyte that has granules in its cytoplasm
     subtype:  monocyte  a type of granular leukocyte that functions in the ingestion of bacteria
        subtype:  monoblast  a large immature monocyte normally found in bone marrow
     subtype:  basophil__basophile  a leukocyte with basophilic granules easily stained by basic stains
     subtype:  neutrophil__neutrophile  the chief phagocytic leukocyte; stains with either basic or acid dyes
        subtype:  microphage  a neutrophil that ingests small things (as bacteria)
     subtype:  eosinophil__eosinophile  a leukocyte readily stained with eosin
  subtype:  packed_cells  a preparation of blood cells separated from the liquid plasma; "packed cells are given to severely anemic patients in order to avoid overloading the circulatory system with too much fluid"
  subtype:  red_blood_cell__redbloodcell__RBC__erythrocyte  a mature blood cell that contains hemoglobin to carry oxygen to the bodily tissues; a biconcave disc that has no nucleus
     subtype:  megalocyte__macrocyte  abnormally large red blood cell (associated with pernicious anemia)
     subtype:  megaloblast  abnormally large red blood cell present in pernicious anemia and folic acid deficiency
     subtype:  acanthocyte  an abnormal red blood cell that has thorny projections of protoplasm
     subtype:  microcyte  an abnormally small red blood cell (less than 5 microns in diameter)
     subtype:  reticulocyte  an immature red blood cell containing a network of filaments or granules
     subtype:  sickle_cell  an abnormal red blood cell that has a crescent shape and an abnormal form of hemoglobin
     subtype:  siderocyte  an abnormal red blood cell containing granules of iron not bound in hemoglobin
     subtype:  spherocyte  an abnormal spherical red blood cell
     subtype:  target_cell  an abnormal red blood cell with a ringed appearance; associated with anemia
