What is a "white blood cell"?
A white blood cell (WBC) is a type of blood cell that plays a crucial role in the body's immune system. Unlike red blood cells, white blood cells do not carry oxygen but help fight infections and protect the body from diseases. They do this by identifying and attacking harmful bacteria, viruses, and other foreign invaders. White blood cells are less common than red blood cells but are essential for maintaining health. A healthy number of white blood cells is important for effectively responding to infections and other health threats.
