The correct term for "white blood cells" is?

The term "white blood cells" refers specifically to leukocytes, which play a crucial role in the immune system. Leukocytes are essential for defending the body against both infectious disease and foreign invaders. They can be found in various types, including lymphocytes, neutrophils, monocytes, eosinophils, and basophils, each with distinct functions in immune response.

Erythrocytes are another term, but they refer specifically to red blood cells, which are responsible for transporting oxygen from the lungs to tissues and facilitating carbon dioxide removal. Thrombocytes, or platelets, are important for blood clotting and help to prevent bleeding, while plasma cells are a type of immune cell that produces antibodies but do not refer to the broader category of white blood cells. Understanding these distinctions emphasizes the importance of leukocytes within the context of the body's defense mechanisms.
