    White blood cell.
  23. lymphocyte
    Mononuclear leukocyte that produces antibodies.
  24. macrophage
    Monocyte that migrates from the blood to tissue spaces. As a phagocyte, it engulfs foreign material and debris.
  25. megakaryocyte
    Large platelet precursor cell found in the bone marrow.
  26. monocyte
    Leukocyte with one large nucleus. It is a cell that engulfs foreign material and debris. Monocytes become macrophages as they leave the blood and enter body tissues.
  27. mononuclear
    Pertaining to a cell (leukocyte) with a single round nucleus; lymphocytes and monocytes are mononuclear leukocytes.
  28. neutrophil
    Granulocytic leukocyte formed in bone marrow. It is a phagocytic tissue-fighting cell. Also called a polymorphonuclear leukocyte.
  29. plasma
    Liquid portion of blood; contains water, proteins, salts, nutrients, hormones, and vitamins.
  30. plasmapheresis
    Removal of plasma from withdrawn blood by centrifuge. Collected cells are retransfused back into the donor. Fresh-frozen plasma or salt solution is used to replace withdrawn plasma.
  31. platelet
    Small blood fragment that collects at sites of injury to begin the clotting process.
  32. prothrombin
    Plasma protein; converted to thrombin in the clotting process.
  33. reticulocyte
    Immature erythrocyte. A network of strands (reticulin) is seen after staining the cell with special dyes.
  34. Rh factor
    Antigen on red blood cells of Rh-positive (RH+) individuals. The factor was first identified in the blood of a rhesus monkey.
  35. serum
    Plasma minus clotting proteins and cells. Clear, yellowish fluid that separates from blood when it is allowed to clot. It is formed from plasma, but does not contain protein-coagulation factors.
  36. stem cell
    Unspecialized cell that gives rise to mature, specialized forms. A hemotopoietic stem cell is the progenitor for all different types of blood cells.
  37. thrombin
    Enzyme that converts fibrinogen to fibrin during coagulation.
  38. thrombocyte
