Study Notes

  • White blood cells, or leukocytes, are a crucial component of the immune system in addition to red blood cells, platelets, and plasma.
  • Neutrophils, one of the five major types of white blood cells, ingest and kill harmful invaders through a process called phagocytosis.
  • Basophils release histamine, a chemical that dilates blood vessels and increases blood flow to transport more white blood cells to the infected site.
  • Eosinophils play a role in combating parasites.
  • Lymphocytes produce antibodies to fight invaders.
  • Monocytes, often referred to as the "garbage trucks" of the immune system, clean up dead or damaged cells and microorganisms.

Test your knowledge of the functions of different types of white blood cells in the immune system. Learn about neutrophils, basophils, eosinophils, lymphocytes, and monocytes.
