  • Erythrocyte (red blood cells)
    Erythrocyte (red blood cells)
    Disc shape: Lack of organelles or nucleus occurs during cell development- important for the exchange of gas - provides more space due to bi-concave of shape.
  • Reticulocytes:
    Reticulocytes:
    Blood cells that have specs: bloods cells that have not completely been broken-down.
  • Species Variation
    Species Variation
    Nonmammals: typically elliptical-shaped (elliptocytes)
  • Nucleated
    round to oval, heterochromatic, centrally placed
  • Thrombocytes (cells that break off)
    Thrombocytes (cells that break off)
    Circulate for 5-6 days 40% stored in spleen
  • Granulocytes
    Granulocytes
    Distinguishing of different blood stains.
  • Eosinophil
    Eosinophil
    As granules mature they are able to attack specific pathogens in Eosinophil (granules are less specific in marrows)
  • Non-Granulocyte: Monocyte (less common)
    Non-Granulocyte: Monocyte (less common)
    Non-segmented nucleus: lobed deeply indented: they become macrophage
  • Monocytes
    Monocytes
    Elicited: Phagocytes or breakdown cells that have died and need to be broken-down.
  • Lymphocyte
    Lymphocyte
    round in shape (relate to activity): Active lymphocytes have more cytoplasm
  • Non-Granulocyte: Monocyte
    Non-Granulocyte: Monocyte
    Non-segmented nucleus, Typically deeply indented, Or lobed (bi-lobed, tri-lobed)
  • Non-Granulocyte: Monocyte
    What is slightly larger than other WBCs, lacks distinctly stained granules and basophilically stained cytoplasm with clear vacuoles (lysosomes)
  • Non-Monocyte
    This Non-Granulocyte Circulates in blood stream for up to several days, also known as a macrophage.
  • Elicited monocyte/phage engulfs & breakdowns cellular and extracellular foreign substances such as
    BacteriaFungiProtozoansVirusesTransformed cellsDying cellsCell debris
  • Non-Granulocyte: Lymphocyte
    Non-segmented round nucleus, Sometimes w/ small indentation (seen ultrastructurally), Active lymphocytes have more cytoplasm
    Non-segmented round nucleus, Sometimes w/ small indentation (seen ultrastructurally), Active lymphocytes have more cytoplasm
  • Non-Granulocyte: Lymphocyte
    Numerous short pseudopodial processes: amoeboid movement, cellular interaction (ex. cancer cells)
  • Non-Granulocyte: Lymphocyte (Two types, T and B)
    Cannot differentiate without IHC. Association with monocyte/macrophage (Mo/Ma)
  • Non-Granulocyte: Lymphocyte
    Non-Granulocyte: Lymphocyte
    Size varies for each sp: divided into small, large, & sometimes medium categories
  • Lymphocyte vs Thrombocyte (nonmammalian)
    Lymphocytes identical to mammals –difficult to distinguish from thrombocytes when small
