Which term denotes white blood cells used for immune defense?

Explanation:
White blood cells, or leukocytes, are the cells of the immune system that defend the body against infection. They come in several types (like neutrophils, lymphocytes, and monocytes) that can recognize pathogens, engulf them, produce antibodies, or coordinate the immune response. This distinguishes them from erythrocytes, which are red blood cells that carry oxygen and carbon dioxide; platelets, which help with blood clotting; and plasma, the liquid portion of blood that transports nutrients and proteins but is not a cell. So, leukocytes are the white blood cells used for immune defense.
