Which term is NOT one of the five main white blood cell types?

• A. Erythrophil
• B. Neutrophil
• C. Lymphocyte
• D. Monocyte

Answer: (A)

White blood cells are named in five main types that carry out distinct immune roles: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. The term that does not fit this set is erythrophil, because the prefix erythro- refers to red blood cells (erythrocytes), which are not white blood cells. Red blood cells are responsible for oxygen transport and lack the immune functions of WBCs. So the correct idea is that erythorphil isn’t a recognized white blood cell type, whereas neutrophil, lymphocyte, and monocyte are legitimate WBC types.
