Leukocytes are capable of amoeboid movement. They are made by the bone marrow and can produce antibodies and move through the walls of vessels to migrate to sites of injury, where they isolate and destroy dead tissue, foreign protein, and bacteria. Types of leukocytes include lymphocytes and monocytes/macrophages, which are agranular, and neutrophils, eosinophils, and basophils, which are all granulocytes. The population of white blood cells (about 6,000 per mm3) is made up roughly as follows: neutrophils (60–70%), lymphocytes (20–25%), monocytes (3–8%), eosinophils (2–4%), and basophils (0.5–1%).
