Monocytes are a type of white blood cell, they range from 13 μm to 25 μm in diameter and are distinguishable from their kidney-shaped nucleus. Monocytes originate from the common myeloid progenitor which differentiates to become a granulocyte and then a monocyte. Monocytes are a phagocytic cell found in the blood, they enter tissues and differentiate to form phagocytic Macrophages. Once matured monocytes are often found in the lymph nodes, spleen, bone marrow, and loose connective tissue. One key role monocytes play in immunity is the ability to differentiate into 2 different cell types - dendritic cells & tissue macrophages.
