Lymphocytes, granulocytes, and macrophages are key white blood cells involved in immune defense.
Lymphocytes play a major role in immunity by defending the body against foreign invaders. They encompass B cells, T cells, and natural killer cells, which collectively contribute to the adaptive immune response.
Granulocytes like neutrophils, eosinophils, and basophils serve as first responders during injury or infection. Monocytes evolve into macrophages and dendritic cells, actively participating in responding to infections or injuries.
For example, macrophages can both phagocytize pathogens and produce inflammation-promoting chemicals, showcasing their pivotal role in the immune response.
