    Study Notes

    Formed Elements of Blood

    • Consist of cells and cell fragments
    • Include erythrocytes, leukocytes, and thrombocytes

    Erythrocytes (Red Blood Cells)

    • Most common of the formed elements
    • Function: undefined in the provided text

    Leukocytes

    • Least common of the formed elements
    • Types:
      • Monocytes
      • Lymphocytes
      • Basophils
    • Abundance: not specified in the provided text

    Monocytes

    • Large, irregularly-shaped cells
    • Irregularly-shaped nucleus (not segmented or multi-lobed)
    • Light-colored cytoplasm, granules not visible
    • Some have vacuoles
    • Phagocytic when transformed into macrophages

    Lymphocytes

    • Usually smaller, very round cells
    • Darker nucleus occupying most of the cell
    • Very little cytoplasm

    Basophils

    • Large cells filled with deep-purple granules
    • Nucleus is not visible ("masked")

    Platelets (Thrombocytes)

    • Function: undefined in the provided text
