Quizplus · Accepted Answer

Leukocytes, also known as white blood cells, are part of the body's immune system and their primary function is to defend the body from nonself agents such as foreign invaders, pathogens, and cancer cells. They do this by identifying and neutralizing or eliminating these threats through various mechanisms such as phagocytosis, producing antibodies, and releasing chemicals. While some leukocytes may also specifically target parasites, their overall function is to protect the body from any potential harm.
