White Blood Cell Quiz Review Cheat Sheet
- White blood cells (leukocytes) - These mighty cells are your body's personal security squad, always on the lookout for invading germs and diseases. They patrol tissues and blood, ready to pounce at the first sign of trouble.
- The five WBC types - Your immune team has five superstar members: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each one has a specialized role, from gobbling bacteria to coordinating complex cellular warfare.
- Neutrophils - Think of these as the SWAT team of infection-fighters: they rush to bacterial and fungal invasions and engulf enemies by the billions. Their phagocytosis powers are unmatched, making them the most abundant WBCs.
- Lymphocytes - This duo consists of B cells, which craft bespoke antibodies, and T cells, which hunt down infected or rogue cells. Together, they orchestrate a targeted strike and long-term immune memory.
- Monocytes - These large cells roam the bloodstream, then transform into macrophages upon entering tissues. They're the cleanup crew, engulfing pathogens and cellular debris like a pro.
- Eosinophils - Parasites don't stand a chance against eosinophils, and they also play starring roles in allergy flare-ups. They release toxic proteins to blast multicellular invaders and signal other immune cells.
- Basophils - When allergies strike, basophils unleash histamine, dialing up inflammation to help battle the perceived threat. They're the dramatic actors of your immune system, ensuring everyone knows an immune response is under way.
- Hematopoiesis - All WBCs are born in the bone marrow through a process called hematopoiesis, where stem cells specialize into different immune heroes. It's the ultimate cell factory, cranking out millions of defenders every day.
- Normal WBC count - A healthy person usually has between 4,500 and 11,000 white blood cells per cubic millimeter of blood. Staying in this range means your immune system is on balanced, vigilant patrol.
- Leukocytosis - When your WBC count soars above normal, it's called leukocytosis, and it often signals an active infection or inflammation. Doctors use this red flag to zero in on what's causing your immune system to rev up.
