leucocytes
Blood's immune soldiers
Leucocytes are white blood cells—the cells of the immune system that defend the body against infection and disease.
They circulate in blood and lymph, identifying and destroying pathogens, foreign substances, and abnormal cells.
The spelling leucocytes is standard in British English; Americans typically write leukocytes.
