Leukocytes that respond to nonspecific foreign invaders are called while respond to specific invaders

Leukocytes that respond to nonspecific foreign invaders are called phagocytes while lymphocytes respond to specific invaders.

Leukocytes are part of the body's immune system. These help the body fight infections and other diseases. The two main groups of leukocytes are phagocytes and lymphocytes.

Phagocytes are cells present in the blood and other animal tissues capable of capturing microorganisms and cell debris (in general, all kinds of particles that are useless or harmful to the organism) and eliminate them, in a process known as phagocytosis

For its part, the main function of lymphocytes is the regulation of the adaptive (or specific) immune response, reacting against foreign materials (microorganisms, tumor cells or antigens in general).
