The type of blood cells responsible for destroying disease-causing microorganisms is white blood cells. These cells, also known as leukocytes, play a crucial role in the immune system. They are essential for defending the body against infections and diseases. White blood cells identify and eliminate pathogens such as bacteria, viruses, and other foreign invaders through various mechanisms, including phagocytosis, where they engulf and digest the microorganisms, and the production of antibodies that target specific pathogens.

While red blood cells are primarily involved in transporting oxygen throughout the body and carbon dioxide away from tissues, platelets mainly aid in blood clotting to prevent bleeding. Plasma cells, which are a type of white blood cell, specifically produce antibodies but are just one subset of the wider group of white blood cells that collectively perform various functions in immune response. Thus, the overarching category that encompasses the primary defenders against disease-causing microorganisms is indeed white blood cells.
