Final answer:
Leukocytes are not called platelets. Leukocytes are white blood cells that protect the body against pathogens, while platelets are cell fragments involved in clotting and repairing blood vessels.
Step-by-step explanation:
No, leukocytes are not called platelets. Leukocytes, also known as white blood cells (WBCs), are a major component of the body's immune system. They protect the body against pathogens and clean up debris. Platelets, on the other hand, are essential for the repair of blood vessels and clotting. They are cell fragments and not the same as leukocytes.
