The average lifespan of WBCs circulating in the blood is 13 to 20 days. The lifespan of different WBCs varies:
  • Granulocytes, especially neutrophils: These WBCs remain in the blood for a few hours to a few days.
  • Monocytes: These WBCs remain in the blood for a few days before they settle in the tissues to become macrophages, where they remain for months.
  • Lymphocytes: These WBCs are vital for the immune memory. They remain for years.
