Study Notes

Whole Blood Composition

  • Blood cells consist of three main components: erythrocytes (RBC), leukocytes (WBC), and thrombocytes (platelets)

Erythrocytes (RBC)

  • 3.9 to 5.5 million per microliter (μL) in women
  • 4.1-6.0 million/μL in men
  • Average lifespan of 120 days

Leukocytes (WBC)

  • Consist of two main types: granulocytes and agranulocytes

Granulocytes

  • Neutrophils
    • 54% to 62% of WBC
    • Active phagocytes that engulf bacteria
    • Half-life of 6 to 8 hours in blood, 1 to 4 days in connective tissues
  • Eosinophils
    • 1% of blood leukocytes
  • Basophils
    • Rare type of WBC

Agranulocytes

  • Lymphocytes
    • Important for defenses against invading microorganisms, parasites, and abnormal cells
    • Lifespan varies from a few days to many years
  • Monocytes
    • Mature into macrophages, which are antigen-presenting cells

Thrombocytes (Platelets)

  • Small, anucleate cells, 2 to 4 μm in size
  • 150,000 to 400,000/μL
  • Lifespan of approximately 10 days
