The Army Inside You: White Blood Cells at Work

  1. White blood cells make up less than 1% of your blood—but they’re mighty.
  2. Neutrophils rush in first, acting as the immune system’s emergency responders.
  3. Lymphocytes handle long-term defense and memory.
  4. Monocytes morph into macrophages, engulfing invaders whole.
  5. Eosinophils specialize in fighting parasites and managing allergies.
  6. Basophils release histamine, triggering inflammation when needed.
  7. Natural killer cells target infected or cancerous cells directly.
  8. Every drop of blood carries thousands of these micro-warriors.
  9. They communicate through chemical “texts” called cytokines.
  10. Their teamwork keeps you healthy even when you don’t notice the battle.
