There are different types of white blood cells, each with a specific role in fighting infection:
* Neutrophils are the most common type and act as "first responders," engulfing and destroying bacteria and fungi.
* Macrophages are larger and longer-lived than neutrophils. They also engulf and destroy pathogens, but they also present parts of the pathogen to other immune cells, helping to activate a more targeted immune response.
* Lymphocytes include B cells and T cells, which play a more specific role in fighting infection.
* B cells produce antibodies, which bind to pathogens and mark them for destruction.
* T cells directly kill infected cells or activate other immune cells.
So, while all white blood cells fight germs, each type has its own unique way of doing so!
