Quizplus · Accepted Answer

Monocytes are a type of white blood cell that circulates in the bloodstream for only a day or two before leaving and entering tissues where they differentiate into macrophages, which are large phagocytic cells that help to engulf and digest foreign substances in the body. Eosinophils and basophils are also types of white blood cells, but they do not differentiate into macrophages. Lymphocytes are another type of white blood cell, but they are not phagocytic and do not differentiate into macrophages.
